I really just want to be a scholar

Chapter 730 Defective All-light Alloy! -
Crack at 25°C? !

This... how is this possible!

Academician Duan Yonggong couldn't believe the results of this investigation.

It should be known that although this kind of all-light alloy does not meet the standard that the low-temperature alloy steel specially used to manufacture liquefied petroleum gas and liquefied natural gas storage and transportation containers can be used below -196°C, it was also thought of at the time of design. It is used in the Northeast, and the cold-resistant temperature design requirement is to reach -50°C. Except for Mohe Town, it can be used almost all over the country!

Now it cracks at -25°C? !
Could it be that something went wrong in the factory?

Academician Duan Yonggong hurriedly arranged for people to go to the factory that ordered this all-light alloy to get the original material for testing, and at the same time led a team to investigate more than 20 counties and districts where the lowest temperature fell below -25°C. Both the "J-92 breakwater" for soft soil and the "J-93 breakwater" for hard soil have cracks in large or small!
Apparently something is wrong with all the light alloys used in it!

Duan Yonggong broke out in a cold sweat. Once the spring or summer floods entered, such a cracked dam with structural signs of collapse would be impossible to prevent the torrential flood!

Duan Yonggong was so worried that he couldn't even sleep when he thought that twenty or thirty counties might become Zeguo and the huge casualties that would be caused.

The researcher sent to the factory to get the original material soon completed the test. Sure enough, all light alloys are not resistant to low temperature, and not only are they not resistant to low temperatures of -25°C, even fine cracks will appear below -10°C. It's just that the cracks are very obvious when it reaches -25°C!

In other words, this all-light alloy can't even reach the cold resistance temperature index of -10°C!It is far from the design requirement of -50°C!
Duan Yonggong was furious, and personally led a team to the cooperative factory to investigate and pursue responsibility. As a result, an even more astonishing thing happened. The factory actually produced this all-light alloy strictly according to the synthesis plan, and all processes were without any problems!
The real problem lies in the synthesis scheme!

Academician Duan Yonggong is not good at materials science. This all-light alloy was originally commissioned by the Light Metal Materials Research Institute under the Xia Ke Academy.

Academician Duan Yonggong was frightened and angry, and rushed to the Institute of Light Metal Materials without stopping.

The Institute of Lightweight Metal Materials also attaches great importance to this matter, and found the personnel who undertook this research project to conduct a detailed investigation, only to find that the person in charge of the project had falsified several indicators in the experimental report that year, among which The hardness and toughness are good, only about 5% lower than the design index, which is not too serious, but the most serious fraud is the low temperature resistance index, which can only withstand -5°C in fact, and a 0 is abruptly added at the end!

It is precisely because several indicators have been falsified that the price of this all-light alloy is half that of ordinary steel!
This is a big problem!

However, Professor Ding Renjun, who was in charge of this project at the time, resigned and went abroad more than a year ago. At that time, seven researchers in the team also resigned. The remaining researchers were just newbies at that time. They do not have the right to access the experimental data, let alone know about the falsification.

Duan Yonggong also tracked down the researcher who was responsible for the acceptance of this all-light alloy project in the Experimental Institute of Fluid-Solid Interaction Mechanics, but he also resigned long ago and disappeared!

This matter suddenly became confusing. It was Ding Renjun who found out that he could not complete the research commission and had to bribe the researchers of the Experimental Institute of Fluid-Structure Interaction Mechanics to cheat together, or it was a pre-arranged conspiracy to wait for high quality and high price. After the cheap and convenient "J-92 Breakwater" plan was widely promoted and implemented in the north, it suddenly collapsed and made countless counties in the north of Xia Kingdom become Ze Kingdom?
No one will ever know the truth.

Duan Yonggong didn't bother to investigate this matter anymore. He reported the case in a hurry, and then chased after the Institute of Light Metal Materials, asking them to complete the original commission and improve the model "MAT-0020" as quickly as possible. All light alloys make it meet the original design index requirements.

The Institute of Lightweight Metal Materials spread their hands and said they were at a loss. They had arranged experts to study and found that although the design idea of ​​the "MAT-0020" all-light alloy was correct at the time, there were indeed unsolvable problems. I want to continue It is too difficult to conduct research and solve the low temperature resistance index problem. It is more practical to spend another year or two to design a new material that fully meets the "J-92 Breakwater" plan.

But how could Academician Duan Yonggong wait another year or two?

Now there are only three or four months left before the spring floods in April and May, and the problematic dams must be repaired before then, otherwise the consequences will be disastrous when the flood season arrives!

However, if other off-the-shelf low-temperature steels on the market are replaced, the indicators such as hardness, toughness, and corrosion resistance may not meet the "J-92 Breakwater" plan. At that time, the entire plan will have to be greatly changed, and it will take at least a lot of time. It's been a year or two.

While Academician Duan Yonggong was struggling to think of ideas everywhere, the news that the core material of the "J-92 Breakwater" scheme had obvious problems spread, and all the regions that adopted the "J-92 Breakwater" scheme They became nervous and put pressure on Academician Duan Yonggong, especially those counties in the north with obvious cracks in the dams, asking him to solve it in the shortest possible time, such as replacing with a new alloy material that is safer and more reliable, and can withstand ultra-low temperatures of -50°C Otherwise, they will adopt other dam design schemes, and Academician Duan Yonggong and his laboratory will be responsible for all losses.

If losing money can solve the problem and avoid the terrible scene of floods during the flood season, academician Duan Yonggong will admit that even if he loses his fortune, he will give priority to compensation according to the contract.

But he has already asked, no domestic dam solution provider is sure to complete the replacement of the dam within three months and it will be safe, so no one will grab the business, but it will inevitably be gloating.

Academician Duan Yonggong is also very helpless about this. In fact, he has been in the limelight over the years. The "J-92 Breakwater" scheme with low price, high quality and short construction period easily defeated the low efficiency, time-consuming, long-term and high-cost embankment in traditional counties. The architectural design scheme has become the first choice for many counties in China to renovate or build dams, and only foreign countries have comparable design schemes.

However, foreign dam design fees are much higher. At the beginning, Duan Yonggong was unwilling to hand over the dam design plan that was related to the safety of the people in his own country to foreign experts, and they ruthlessly earned a large amount of design fees. , A research group was formed to specialize in this "J-92 Breakwater" program.

Who would have thought that the core material would be severely pitted?
At this moment, the twenty-odd northern counties put forward alternative plans one after another, and all of them were designed and provided by foreign companies, and these foreign design companies all stood behind the shadow of the same multinational company!
The design and implementation prices of these alternatives are outrageous, five times more expensive than the original "J-92 Breakwater" proposal by Academician Duan Yonggong!
Five times!

Even if Academician Duan Yonggong sold the equipment of the entire research institute and all the patents in his hands, he would not be able to afford the compensation claims of the twenty-odd northern counties!

At this time, Academician Yonggong finally realized that he had stepped into a trap that had been prepared long ago, and the opponent's target should not be him, but his current market position!

Whether it is to smash the conspiracy of this cunning and shameless multinational corporation, or to continue his scientific research and academic career, academician Duan Yonggong can't bow his head, he can only grit his teeth and find a way.

In the end, considering the possible adverse effects, Academician Duan, who has always been proud, had to bow his head, and asked for help from Vice President Wen Xuanping of the Xia Ke Academy, and explained the ins and outs of everything in detail.

The Vice President Wen of the Xia Ke Academy couldn't sit still when he heard it. He thought the "J92-Breakwater" project was very good, so he strongly supported the promotion of it. He was completely selfless and did not receive any benefits.

Now that the original good intentions have turned into bad things, and the dams protecting millions of people have such serious problems, Academician Wen Xuanping also feels a headache, so he has to take Academician Duan to report to the big boss Yang Chengke.

Lao Yang also attached great importance to it, and hurriedly asked the secretary to call experts in related fields to a meeting to discuss the fastest and best solution. He also has profound attainments in this area, so he begged to invite these two young professors to attend the meeting...

After listening to Academician Duan Yonggong's indignant statement, Qin Ke finally understood what happened. When this happened to him, he would naturally not stand idly by.

But the research and development of a new material is not an easy task, especially the Institute of Lightweight Metal Materials is very high-level, they are helpless, and Qin Ke is not fully sure to solve this problem within a mere month.

Yes, although the flood season is still three or four months away, considering that the research will be handed over to the factory for production and added to the "J-92 Breakwater" program for testing, it will have to be released within a month at the latest. After the research, one month is also the deadline for academician Duan to reply from the twenty-odd northern counties.

Seeing that Qin Ke was pondering and didn't reply, Academician Wen Xuanping next to him sighed: "The Institute of Lightweight Metal Materials under the Xia Ke Academy is already one of the top alloy research institutes in China. They can't solve it. Tomorrow's meeting I’m afraid not many people will be able to stand up and solve this problem.”

"I hope there will be a brave man under the reward." Academician Duan Yonggong said bitterly: "I have made a promise, no matter who can solve this problem, I will combine the 'J-92 Breakwater' plan with the 'J-93 I will share half of the patent fee proceeds from the breakwater project with him, and donate the remaining half. Then I will donate these two patents to the country free of charge, as a way to make up for my mistakes. It was my negligence to personally participate in the final test of the 'MAT-0020' all-light alloy." In fact, he can't be blamed for this, after all, the Institute of Lightweight Metal Materials has a very high voice, and who would have thought that such a top-notch institute would Will there be professors who blatantly cheat?
Academician Duan Yonggong also said this to Qin Ke, saying that he did not ask Qin Ke to help for free.

Qin Ke waved his hand: "Let's not talk about these things. Since this matter is related to the safety of millions of people, I naturally have no reason to back down. I also don't want to see the conspiracy of foreign companies succeed."

These foreign design companies have really opened up the domestic market. In the future, they will go everywhere under the banner of designing dams and conduct various investigations on the rivers and lakes of Xiaguo. Qin Ke does not want to see such a situation.

Qin Ke asked again: "Academician Duan, can you show me the relevant information first?"

"No problem." Academician Duan Yonggong pushed a thick stack of materials in front of Qin Ke: "Professor Qin, please take a look first. I originally planned to disclose these materials at the meeting tomorrow."

At the beginning, Academician Duan Yonggong directly bought out all the materials of this all-light alloy with the model "MAT-0020". These materials contained all the research data and the final synthesis plan, which were originally commercial secrets and could not be disclosed to the outside world, but at this time Knowing that there are falsified data in these materials, the importance will naturally drop significantly. Academician Duan really intends to make it public at tomorrow's meeting, even if it is to make some contributions to domestic materials science.

After all, although the hardness, toughness, corrosion resistance and other indicators of this all-light alloy are a bit behind his design requirements, it is considered advanced in China, and its weight is half that of ordinary steel, but its cost is lower than that of ordinary steel. Steel is half the price.If it is used in an environment above -5°C, it is still very useful.

Qin Ke took it, and concentrated on reading it all at a speed of one glance and ten lines in about 15 minutes.

He does have master-level chemical knowledge in his mind, and naturally he has material science knowledge that is not inferior to most professors, but having knowledge and being able to create a new material are completely different things. How many senior professors have devoted their entire lives to researching a new material A new material?

After reading these materials, although Qin Ke was familiar with the "MAT-0020" all-light alloy, he did find that there were problems and signs of data tampering in more than a dozen details in it, but he couldn't find it right away. Find a solution.

The most important problem to be solved for normal low-temperature alloys is the toughness at ultra-low temperatures, which is generally achieved by infiltrating Ni, Zr, Ti, Nb and other alloying elements to refine the grains, but how many trace elements are infiltrated is very important. For example, Ni will enhance the thermal cracking tendency of the material during welding and change the stress distribution inside the alloy.

Even if Qin Ke has extraordinary mathematical ability, he still needs to conduct continuous experiments through huge experiments and obtain experimental data before he can analyze, model, and deduce.

It's been a bit of a stretch for a month.

Qin Ke suddenly thought of someone, and asked, "Have you invited Academician Song Shiliang from Xia Ke University to attend tomorrow's meeting?"

Academician Song Shiliang is a leader in the fields of superalloys, alloy steels, metal corrosion and protection, metal solidification theory, material fatigue and fracture, amorphous nanocrystals and other metal materials. Because Qin Ke and Ning Qingyun had rescued him once, the relationship between the old academician and the two was very good. He even made a special trip to Qingmu University before, just to explain the relationship between crystal structure and natural stress to them.

This also played a lot of role in Qin Ke and Ning Qingyun's overcoming of the synthesis problem of "Majorana Fermion Carrier-Lime Superconducting No. [-] Material". Qin Ke also expressed special thanks to Over the old academician Song.

Academician Wen Xuanping shook his head and said, "Yes, please. It's just that Academician Song has been unwell recently and has been admitted to the hospital again, so he can't attend the meeting."

Qin Ke was taken aback: "Academician Song is admitted to the hospital? Is it serious?"

"It shouldn't be a serious problem. According to his wife, it's still an old problem of myocardial infarction, but at least he needs to be hospitalized for two or three months."

Qin Ke had visited Academician Song several times in the past two months, taught him the Oriental Yuan-Cultivating Method and formulated a diet therapy plan for him, but the Eastern There were obvious effects within two months, and it was not too unexpected that Academician Song had a relapse and was admitted to the hospital.

Qin Ke decided to visit Academician Song overnight.One is to visit this respected old academician, and the other is to ask if there is a better way to solve this problem.

The dam project, which is related to the safety of millions of people, cannot be delayed or neglected.

After a hasty dinner at Uncle Yang's house, Qin Ke took Chen Ming's car directly to the hospital to visit Academician Song.

……

When Qin Ke went to visit Academician Song, Ding Renjun was giving a report to a blond middle-aged man in a certain laboratory abroad.
