Material Empire

This person in front of him is naturally unknown to Qin Hai in this life, but he is very familiar with Qin Hai in his previous life. 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 an old man half buried in the earth. Qin Hai had worked with this person for more than half a year, and met him many times at academic conferences since then. Of course, this person is not an engineer of the provincial military region's machinery repair institute, but an academician of the Academy of Sciences and the chief engineer of the General Iron and Steel Institute. His name is Chen Heqian.

The Chen Heqian that Qin Hai sees now is only in his 40s, and he is not an academician, but Qin Hai knows that Chen Heqian has already made extraordinary achievements in the research on the properties of metal materials, and is one of the big names in this field in China.

"So it's Chen Gong, I'm sorry."

Qin Hai didn't know why Chen Heqian sat here with his name hidden. Since Yue Guoyang didn't reveal his real identity, Qin Hai naturally couldn't expose it on the spot. If people want to act with me, I just act with me. If you want to reminisce about the old days, there will be opportunities in the future. Also, can this count as reminiscing about the past?

"Comrade Xiaoqin, I studied the steel of the shovel you made and found that its strength far exceeds that of common steel. Can you tell me how this steel is smelted?" Chen Heqian tweeted The glasses on the bridge of the nose started to ask Qin Hai questions.

Actually, the real protagonist of today's scene is not Yue Guoyang, but Chen Heqian. The camp they are in is a missile force base stationed in Anhe Province. Some time ago, during training, the army found that the tail material of a certain type of missile was defective, so they invited local experts to come to diagnose it. It was for this reason that Chen Heqian came here.

Yesterday, after Yue Guoyang got the dagger and engineer shovel from Ge Dongyan, he had been thinking about how to solve the steel problem. He knew that the experts from the General Iron and Steel Institute were in the missile force in the suburb of Hongze, so he came over in person and sent these two products to Chen Heqian for appraisal.

Chen Heqian was shocked when he saw these two things. He asked his assistants to test this steel with instruments, and concluded that the strength of this steel exceeds that of the best alloy steel available in China, especially its high temperature resistance is outstanding. Although this kind of steel cannot be directly used to make missile tail fins, but drawing on the idea of ​​this kind of steel can easily solve the dilemma they are currently facing.

As soon as this conclusion came out, Yue Guoyang was also stunned. Chen Heqian and others have been working on the missile base for two or three months without solving the problem, but they found the answer in a county-level agricultural machinery factory. This is simply too dramatic. Chen Heqian immediately asked to meet the inventor of this steel, and at this time the results of the investigation by the Political Department also came back, showing that Qin Hai had no political problems and was a person with access to a certain level of military secrets. Yue Guoyang immediately decided to send Zhu Chongwu to Qingfeng Agricultural Machinery Factory, and transferred Qin Hai to the provincial military region to assist in the work.

Of course, Qin Hai didn't know about these situations. However, when he recognized Chen Heqian, he knew that Yue Guoyang had summoned him here definitely not because of an engineering shovel, and it was definitely not an easy project for Chen Heqian to come forward.

After understanding this verse, Qin Hai didn't bother to play tricks anymore. It's just a formula for ultra-high-strength steel, so it doesn't matter if it's a gift for an old friend. He smiled slightly and said: "Mr. Chen, the steel I smelted is not a new technology. I just imitated the smelting ideas of H11 and H13, two heat-deformed die steels, and improved the alloy quality through secondary hardening. It's just the strength of steel."

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

"This is because I have adopted a special high-temperature tempering process to disperse and precipitate special carbides such as M7C3, M2C, and MC in the steel, which can increase the secondary strengthening effect." Qin Hai responded eloquently.

"How is the ductile-brittle transition temperature of steel lowered?"

"Accomplished by adding the right amount of nickel, while also being able to increase the hardenability of the steel."

"How did you design the heat treatment process?"

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

"...Are you really a graduate of the Agricultural Machinery Technical School?" Chen Heqian looked at Qin Hai in horror, with all kinds of expressions on his face intertwined, which was beyond description.

"Uh... Did I say a little too much?" Qin Hai smiled wryly.

After answering the question just now, Qin Hai had long forgotten his time-traveling identity, and seemed to be back before time-traveling. At that time, every time he was with Chen Heqian, he would ask and answer like this, and his thoughts jumped so fast that the observers couldn't react. However, at that time, Qin Hai was a postdoctoral fellow of the Institute of Materials Science and Technology, and had the ability to talk to Chen Heqian. Now Qin Hai is just a technical school student, and what he said made the chief engineer of the General Iron and Steel Institute feel unbelievable. This is simply a monster !

"Do you understand?" Chen Heqian asked, turning his head to the people nearby.

There are several assistants brought by Chen Heqian on this trip, including graduate students who are studying, and assistant engineers who are already working. During the dialogue between Chen Heqian and Qin Hai, they could grasp some concepts at the beginning, but soon fell into complete confusion. The questions Chen Heqian raised are all important links in technology. When Qin Hai answered, he also left the process behind and only mentioned the key concepts. This kind of dialogue between top experts does not go back to the principles. Often only one word is needed to make the other party understand their own ideas, and the rest only needs to be complemented by each other.

"Mr. Chen, I didn't understand something." An assistant replied dully, "However, I have written down what you and Teacher Qin said just now."

Teacher Qin!

Accompanied by him was an engineer from the missile force, his eyes widened bigger than a copper bell when he heard the assistant's words. Chen Heqian is an approachable expert, but among the assistants around him, there are those who look above the top. This is the case with the one who spoke just now. During this time in the army, in addition to appearing honest in front of Chen Heqian, don't be too pushy in front of the engineers in the army.

However, it is such a dragging person who actually calls this childish young worker a teacher, this world is really incomprehensible.

"Commander Yue, the level of your technical school is so high?" Chen Heqian turned his head to ask Yue Guoyang for proof. He was not a person who knew how to fake, but after being shocked by Qin Hai's knowledge, he even forgot the one that Yue Guoyang made up for him. False identity, as soon as he speaks, he shows his feet.

Yue Guoyang desperately blinked at Chen Heqian, and said, "Old Chen, the level of our agricultural machinery technical school is quite good, didn't you go?"

"It's amazing, it's amazing." Chen Heqian murmured, "A student trained by an agricultural machinery technical school has such a strong theoretical foundation, talent, talent!"

"Teacher Chen has won the award." Qin Hai hurriedly bowed his hands to thank Chen Heqian. He knew that what he said had convinced Chen Heqian. He has knowledge decades ahead of his time. Some content may not be regarded as great knowledge by professionals of later generations, but in this era, it is a very avant-garde theoretical innovation.

"I've been chatting all morning, are you hungry? Come on, let's set the table and let's chat while eating." Yue Guoyang stood up and greeted everyone.

Chen Heqian is a national expert, and Yue Guoyang has always respected him. Qin Hai was able to make Chen Heqian feel admiration, and Yue Guoyang naturally regarded Qin Hai as an expert, and no longer treated him as a young worker. Seeing that the conversation between the two sides came to an end, Yue Guoyang remembered his role, and began to arrange a banquet. Of course, the main purpose was to entertain Chen Heqian, and Qin Hai was just enjoying the glory.

There were a few tall trees beside the lake, according to Yue Guoyang's order, the dining table was arranged under these big trees, which was shady and open, which was in line with the tradition of soldiers.

Several guard soldiers brought the big round table from the cafeteria, propped it up under the tree, and then began to distribute the bowls and chopsticks. Zhu Chongwu led Qin Hai to the table, pointed him to a seat, and said, "Xiao Qin, I think Teacher Chen admires you very much, why don't you sit next to Teacher Chen."

"No problem." Qin Hai nodded, then walked forward and moved the bowl and chopsticks next to his seat a little.

"Teacher Chen, this way please." Yue Guoyang accompanied Chen Heqian and walked over. He pointed to the seat for Chen Heqian and said, "Teacher Chen, please sit here."

Chen Heqian walked to the table and was about to sit down when his eyes accidentally noticed the bowls and chopsticks in front of him, and he couldn't help being taken aback.

"Who set these chopsticks for me?" Chen Heqian asked.

"It's that Comrade Qin." The guard soldier who was serving next to him said, he looked at the position of the bowl and chopsticks, and couldn't help muttering: "This Comrade Qin is really, why did you put your chopsticks on the left hand side... "

"Don't move!" Chen Heqian stopped the guard soldier who was about to move the chopsticks to his right, then turned his head to look at Qin Hai who was beside him, with suspicion in his eyes.

Qin Hai smiled, and stretched out his hand to signal: "Mr. Chen, please take a seat. If I'm not mistaken, you should be used to holding chopsticks with your left hand."

"So you already knew who I was?" Chen Heqian was as shocked at this moment as he was at the moment just now.
