Chapter 839 Too Strong
Vice President Wang's mind was overwhelmed by one question after another.

Following the practice of the Japanese, he proposed adding rhenium to the blades.

The results of the experiment were not satisfactory, and he was ready to bear the consequences.

But the boss not only did not ask the crime, but also brought him a new material that he had never heard of before.

If the person in front of him wasn't his boss, and if the boss's spirit didn't look normal, he would definitely give him a slap to wake him up!
After a while, Vice President Wang heard Yang Dongsheng calling him, "Old Wang, Lao Wang, did you hear me?"

Vice President Wang came back to his senses for a while, thought about what he heard vaguely just now, and then said, "Since this material is sensitive to heat, it should be cut with a water jet! As for which tool to choose for processing, it depends on the test results. Sure!"

Vice President Wang paused, and then said, "If it is true as you said, using this material to make high-pressure turbine blades can save cooling structures and even coatings. Not only can we greatly improve the strength of the blades, but also extend the life of the blades. , can also greatly simplify the engine structure, reduce the difficulty of design, and the entire research and development cycle and research and development costs can be greatly reduced!"

Yang Dongsheng nodded, this is the answer he wanted, "From now on, this material is listed as one of the top secrets of the group! I decided to set up a special working group to take over the application and research and development of this material. The group is temporarily named "Material No. [-] Group", you will be the team leader, and you can recommend other leading members of the group!"

Vice President Wang thought about it and announced several names.

There is the director of Dongsheng Heavy Industry Materials Research Center, the manager and chief engineer of the Turbo Machinery Division, the director and chief engineer of the cemented carbide processing workshop...

"One item came out, take a look!" Vice President Wang smiled wryly.

Before the food was served, he took out his mobile phone and called Zhou Ying, saying that he had something to do in the evening, so they didn't have to wait by themselves.

Yang Dongsheng nodded in approval, and then said, "From now on, all members who join this group must go through a strict review!"

Vice President Wang introduced Yang Dongsheng, who were the members of the leadership team identified just now.

At this time, there were already several people in the conference room.

After all, such a false name won't last long.

The reason why Yang Dongsheng added a question mark after the data of 97HRA is because due to the limitation of the scale of the Rockwell hardness measuring equipment, the measurement data is generally only between 20 and 88HRA.

Yang Dongsheng quickly finished his meal.

The expansion rate of the alloy placed at a depth of 1100 kilometers underground is only 10%, and the expansion rate of the alloy placed at a depth of 1600 kilometers has already reached 30%.

The Rockwell hardness measurement method is to use a certain load to press the tail of a diamond cone with a vertex angle of 120 degrees, and the diamond cone head rushes towards the tested object.

Yang Dongsheng came out of the cafeteria and returned to the meeting room.

These people are the core executives of Dongsheng Heavy Industry. There is no problem with reliability, and the next step of research and development cannot be separated from them.

Yang Dongsheng thought for a while, and placed the alloy sections down one by one at intervals of 100 meters.

This thing is easy to operate and has high reliability. It is a method commonly used in factories to measure hardness and can be used to measure various hard alloys.

But after the copper melted, it seeped into the earth's core at a speed visible to the naked eye.

Besides, the bodyguard who followed him didn't know if he ate or not.

Dongsheng Heavy Industry also works in three shifts, and the cafeteria provides hot food 24 hours a day.

It has been placed underground at a depth of about 1600 kilometers.

The compressive strength also decreases, and the alloy expands even more.

"I'm afraid this test will not produce results for a while!" Vice President Wang stood up and said, "I heard from Lao Li that you haven't had time to eat dinner, why don't you go to our cafeteria to deal with the two? Our food is not bad!"

Yang Dongsheng made some materials that are softer than nickel and iron, have better ductility, and better conductivity, such as copper and aluminum.

"Has the result come out?" Yang Dongsheng asked.

Yang Dongsheng stored these alloy segments in a huge granite body close to the ground.

The test results take 0.002 mm as a hardness unit, and the hardness value is determined by the depth of plastic deformation of the indentation.

But after putting them together, he immediately found something wrong—there was an obvious difference in the expansion rates of these alloys.

Yang Dongsheng thought for a while before he understood.

In less than 10 minutes, the waiter brought up four dishes, including deep-fried prawns, Mushu meat, scrambled eggs with tomatoes, fried vegetables with shiitake mushrooms, and a seaweed shrimp skin soup. The staple food was rice.

It seems that we can only wait for the ability to be further improved and put copper and aluminum deeper.

In addition, Yang Dongsheng thought that in order to make a superconducting magnet, the material must first be made into a wire.

Yang Dongsheng entered a separate private room, and the bodyguard was also greeted.

Yang Dongsheng took a look and frowned immediately, "97HRA?"

Further down, it becomes difficult to find diamonds that are large enough.

After thinking about it carefully, he found that the deeper the formation went, the more the nickel-iron alloy expanded.

Moreover, the composition of diamonds is more complicated as it goes down, and diamonds also contain a lot of heavy metals.

After the aluminum melts, it begins to float upwards.

Yang Dongsheng was about to exit the [-]D map when he suddenly discovered an interesting phenomenon.

Presumably because of the pressure at this depth, the degree to which copper and aluminum are compressed is not enough to allow them to resist the high temperature of the earth's core.

The alloy section obtained before has cooled down.

It's nothing, aluminum has a low density and is liquid on top.

Yang Dongsheng nodded, "Just prepare a few home-cooked dishes!"

He was almost dumbfounded, but the bottom is solid!

The lower the temperature, the higher the temperature. At a depth of 1600 kilometers underground, although the diamonds have not melted, they have softened very severely.

It is estimated that the results of the test have not yet come out, so he took advantage of his spare time to get another batch of alloy segments.

In recent years, due to the advancement of cemented carbide technology, the upper limit of the scale has been exceeded many times, and the scale has been relaxed to 93 to 94HRA.

It's a pity that these materials were placed underground. Although they were obviously compressed, they were eventually melted by high temperature.

As soon as Vice President Wang said, Yang Dongsheng was really hungry.

This is a Rockwell hardness data.

Both nickel and iron have great hardness and poor ductility.

The piece of copper that Yang Dongsheng put down was gone in just a few breaths!

Now that the data of 97HRA is given, this must have exceeded the upper limit of the scale again.

More importantly, the hardness of tungsten carbide tools is only 93HRA, and the Rockwell hardness of diamonds is only 100HRA. This alloy exceeds the hardness of tungsten carbide tools.

Vice President Wang smiled wryly, "I used to use electric discharge forming technology to process this kind of cemented carbide before, but you said that this material will fail after being subjected to too high a temperature."

The meaning of Vice President Wang is obvious. The materials given by Yang Dongsheng are too strong.
