Material Empire

In front of the eyes, Qin Hai of this life is naturally unknown, but Qin Hai of the previous life is more familiar. Of course, when Qin Hai met him in the previous life, he was more than 20 years older than he is now, and he was already a half-entry old man. Qin Hai has worked with this person for more than half a year, and has met many times during academic conferences since then. This person is certainly not an engineer of the Provincial Military Region Repair Equipment Institute, but an academician of the Academy of Sciences and a chief engineer of the Central Iron and Steel Institute, named Chen Heqian.

Chen Heqian that Qin Hai now sees is still in his 40s and is not an academician, but Qin Hai knows that Chen Heqian has made extraordinary achievements in the research of metal material properties at this time, and is one of the big cattle in this field in China.

"It turned out to be Chen Gong, disrespectful."

Qin Hai did not know why Chen Heqian sat here anonymously. Since Yue Guoyang did not reveal his true identity, Qin Hai could not expose it on the spot. If they want to play with themselves, they can accompany them. If you want to retell the old things, there will be opportunities in the future, and still, can this be recounted?

"Comrade Xiao Qin, I researched the steel of the shovel you made, and found that its strength is far beyond that of common steel. Could you please introduce how this steel is smelted?" Chen Heqian pushed and pushed The glasses on the bridge of the nose began to ask Qin Hai.

In fact, the real protagonist of this scene today is not Yue Guoyang, but Chen Heqian. The camp where they are located is a missile force base in Anhe province. Some time ago, during the training, the army discovered that the material of the tail wing of a certain missile was defective, so it invited local experts to diagnose it. Chen Heqian came here for this reason.

Yesterday, after getting the dagger and engineering **** sent by Ge Dongyan, Yue Guoyang has been pondering how to solve the steel problem. He knew that the experts of the Central Iron and Steel Institute were in the missile force in the suburb of Hongze, so he personally came over and gave these two products to Chen Heqian for identification.

Chen Heqian was astonished when he saw these two things. He asked his assistants to test this steel with an instrument, and concluded that the strength of this steel exceeds the strength of the best alloy steel available in China, especially its high temperature resistance. Although this steel cannot yet be used directly to make missile tails, drawing on the ideas of this steel can easily solve their current dilemma.

As soon as this conclusion came out, Yue Guoyang was also stunned. Chen Heqian and others worked hard at the missile base for two or three months and did not solve the problem. They actually found the answer at a county-level agricultural machinery factory, which is simply too dramatic. Chen Heqian immediately asked to meet the inventor of this steel, and the results of the investigation by the Ministry of Politics returned at this time, showing that Qin Hai was politically unproblematic and belonged to personnel who could access certain levels of military secrets. Yue Guoyang immediately decided to send Zhu Chongwu to Qingfeng Agricultural Machinery Factory to negotiate with Qin Hai to the provincial military area to assist in the work.

Under these circumstances, Qin Hai naturally did not know. However, when he recognized Chen Heqian, he knew that Yue Guoyang called himself over, definitely not for the sake of an engineering spade. The project that can make Chen Heqian come forward is definitely not easy.

I understood this section, Qin Hai would not bother to play any more tricks. Just a formula of ultra-high-strength steel, even if it is a meeting gift for an old friend, why not. He smiled and said, "Chen Gong, in fact, the steel I made is not a new process. I just imitate the smelting ideas of two heat-deformable mold steels, H11 and H13, and improve the alloy through secondary hardening. The strength of steel. "

"However, the strength of your steel is obviously higher than H11 and H13." Chen Heqian asked.

"This is because I have adopted a special high-temperature tempering process to diffuse the precipitation of special carbides such as M7C3, M2C and MC, which can increase the secondary strengthening effect."

"How does the ductile-brittle transition temperature of steel decrease?"

"It is achieved by adding an appropriate amount of nickel, while also improving the hardenability of the steel."

"How did you design the heat treatment process?"

"Air cooling at 1010 degrees Celsius, tempering at 550 degrees Celsius, lath martensite structure with high dislocation density can be formed under air cooling conditions ..."

"... Are you really graduated from the Agricultural Machinery Technical School?" Chen Heqian looked at Qin Hai with horrified eyes, and the expressions on his face were intertwined, which was beyond description.

呃 "Uh ... did I say a little bit more?" Qin Hai smiled bitterly.

I answered this question just now. Qin Hai had long forgotten her crossing identity and seemed to be back to before crossing. At that time, every time he was with Chen Heqian, he just asked and answered like this, his thinking jumped so fast that the people who listened could not react. However, at that time Qin Hai was a postdoc in the Institute of Materials and had the ability to talk with Chen Heqian. Now this Qin Hai is just a technical school student. What he said made the chief engineer of the Central Iron and Steel Institute feel incredible. !!

"Did you understand?" Chen Heqian turned his head to a few people and asked.

There are a few assistants beside Chen Heqian during the trip, some are graduate students, and some assistant engineers are already working. During the dialogue between Chen Heqian and Qin Hai, they were still able to grasp some concepts at first, but soon became completely confused. Chen Heqian's questions are important links in technology. When Qin Hai answered, it was also a process away from it, only mentioning the key concepts. This kind of dialogue between top experts does not review any principles. Often only one word is needed to make the other party understand their ideas, and the rest only needs to complement each other.

"Mr. Chen, I don't understand some places," an assistant replied neatly, "but I have written down what you and Teacher Qin said just now."

Teacher Qin!

Accompanying me was an engineer in the missile unit. When he heard the assistant's words, his eyes were wider than that of Tong Ling. Chen Heqian is an easy-going expert, but the assistants around him have the kind of eyes that are higher than the top. This is the case of the one who spoke just now. Except for being more honest in front of Chen Heqian, don't drag too much in front of the army's engineers.

However, it is such a dragging person that he actually called this childish young worker as a teacher, and the world is really confusing.

"Commander Yue, your technical school is so high?" Chen Heqian turned his head to verify with Yue Guoyang. He was not a man who could be a fake. After being shocked by Qin Hai's knowledge, he even forgot the one edited by him False identity, as soon as he speaks, he shows his feet.

Xie Yue Guoyang desperately blinked at Chen Heqian, and said in his mouth, "Lao Chen, the level of our agricultural technical school is pretty good, have you not gone?"

"Amazing, awesome." Chen Heqian murmured, "A student trained by an agricultural machinery technical school has such a solid theoretical foundation, talents, talents!"

"Mr. Chen has won a prize." Qin Hai quickly thanked Chen Heqian, knowing that these things he said convinced Chen Heqian. This is partly because he is an outstanding person and partly because He has decades of knowledge. Some content is not regarded as great knowledge by the professionals of later generations, but in this era, it belongs to very avant-garde theoretical innovation.

"It's been a morning of chatting, are you hungry? Come on, let's put the table on and let's talk as we eat." Yue Guoyang stood up and greeted everyone.

Chen Heqian is a national expert. Yue Guoyang always respects him. Qin Hai was able to admire Chen Heqiandu. Yue Guoyang naturally regarded Qin Hai as an expert and no longer treated it as a young worker. Seeing that the dialogue between the two parties came to an end, Yue Guoyang remembered his role and began to arrange wine banquets. Of course, the main purpose was to entertain Chen Heqian, and Qin Hai just touched the light.

On the edge of the lake, there are several big pavilions ~ www.readwn.com ~ According to Yue Guoyang's order, the dining table is arranged under this big tree, so that it is both cool and open, which is in line with the military tradition.

Several guard soldiers brought a large round table from the cafeteria, supported it under the tree, and then began to distribute tableware. Zhu Chongwu led Qin Hai to the table, pointed him to a seat, and said, "Xiao Qin, I see Mr. Chen appreciates you very much, or you can sit next to Mr. Chen."

"No problem." Qin Hai nodded, then stepped forward and moved the bowl and chopsticks next to his seat slightly.

"Ms. Chen, please." Yue Guoyang accompanied Chen Heqian, and he pointed to Chen Heqian and said, "Miss Chen, please sit here."

贺 Chen Heqian walked to the table, was about to sit down, and noticed the bowl of chopsticks in front of him, and couldn't help but stun.

"Who is the chopsticks I set for me?" Chen Heqian asked.

"It's Comrade Qin," said the guard soldier who was serving next to him. He looked at the position of the chopsticks and couldn't help whispering: "This Comrade Qin is really, how to put your chopsticks on the left hand ... "

"Don't move!" Chen Heqian stopped the guard soldier who was preparing to move his chopsticks to his right hand, and then turned to look at Qin Hai, with suspicious eyes flashing.

Qin Hai smiled, and stretched out his hand to signal: "Ms. Chen please come to the table, if I am not mistaken, you should be used to holding chopsticks with your left hand."

"You already know who I am?" Chen Heqian's shock at this moment was no less than that just now.
