The person in front of him, Qin Hai in this life is naturally unknown, but Qin Hai in his previous life is very familiar. Of course, when Qin Hai met him in the previous life, he was more than 20 years older than now, and he was already a half-cut old man. Qin Hai had worked with this person for more than half a year, and since then, he has met many times at academic conferences, which is a friend who has forgotten his year. Of course, this person is not an engineer from the Provincial Military Region's Repair Institute, but an academician of the Academy of Sciences and the chief engineer of the General Iron and Steel Institute, named Chen Heqian.

Chen Heqian, whom Qin Hai sees now, is only 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 bulls in this field in China.

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

Qin Hai didn't know why Chen Heqian wanted to sit here incognito, since Yue Guoyang didn't reveal his true identity, Qin Hai naturally couldn't expose it on the spot. If people want to act with themselves, they just accompany them to act. If you want to reminisce about the old and something, there will be a chance in the future, and also, can this be considered reminiscence?

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

In fact, the real protagonist of today's scene is not Yue Guoyang, but Chen Heqian. The camp where they are located is a missile unit base stationed in An Ha province. Some time ago, during training, the troops discovered that there was a defect in the tail material of a certain type of missile, so they invited local experts to come to diagnose it, and Chen Heqian came here for this reason.

Yesterday, after Yue Guoyang got the dagger and sapper shovel sent by Ge Dongyan, he has been thinking about how to solve the problem of steel. He knew that the experts of the General Iron and Steel Institute were in the missile unit on the outskirts of Hongze, so he personally came over 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 the conclusion was that the strength of this steel exceeded the strength of the best alloy steel in China, especially its high temperature resistance was outstanding. Although this steel cannot be directly used to make missile tails, the idea of borrowing this steel can easily solve the dilemma they are currently facing.

As soon as this conclusion came out, Yue Guoyang was also stunned. It is simply too dramatic that Chen Heqian and others have been working at the missile base for two or three months and have not solved the problem, but they actually found the answer in a county-level agricultural machinery factory. Chen Heqian immediately asked to meet with the inventor of this steel, and at this time, the results of the investigation by the Political Department also returned, showing that Qin Hai had no problem in politics and belonged to a certain level of military secrets. Yue Guoyang immediately decided to send Zhu Chongwu to Qingfeng Agricultural Machinery Factory to negotiate the transfer of Qin Hai to the provincial military region to assist in the work.

In these situations, Qin Hai naturally didn't know the way. However, when he recognized Chen Heqian, he knew that Yue Guoyang summoned him over, and it was definitely not for a sapper shovel, and the project that could get Chen Heqian to come forward was definitely not simple.

Knowing this section, Qin Hai didn't bother to play any more tricks. It's just a formula of ultra-high-strength steel, even if it's a welcome gift for an old friend. He smiled slightly and said: "Chen Gong, in fact, the steel I smelt is not a new process, I just imitate the smelting ideas of H11 and H13, two kinds of heat deformation die steel, and improve the strength of alloy steel through secondary hardening." ”

"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 from the steel, which can increase the secondary strengthening effect." Qin Hai replied like a stream.

"How does the toughness-brittleness transition temperature of steel decrease?"

"This is achieved by adding the right amount of nickel, while also improving the hardenability of the steel."

"How did you design the heat treatment process?"

"1010 degrees Celsius air cooling, 550 degrees Celsius tempering, under air cooling conditions, can form a high staggered density of slatted martensitic structure......"

“…… Are you really a graduate of an agricultural machinery technical school? Chen Heqian looked at Qin Hai with shocked eyes, and the various expressions on his face were intertwined, which was indescribable.

"Uh...... Am I talking a little too much? Qin Hai smiled bitterly.

In this question just now, Qin Hai had long forgotten his identity as a crossover, and seemed to have returned to before crossing. At that time, every time he was with Chen Heqian, he asked and answered like this, and his thinking jumped so fast that the people who were listening couldn't react. However, at that time, Qin Hai was a postdoctoral fellow of the Institute of Materials, and he had the strength to talk to Chen Heqian, but now this Qin Hai is just a technical school student, and what he said made the chief engineer of the General Iron and Steel Institute feel incredible, this is simply demonic!

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

There are several assistants brought by Chen Heqian on this trip, including graduate students and assistant engineers who are already working. In the process of Chen Heqian's dialogue with Qin Hai, they were able to grasp some concepts at first, but soon they fell into complete confusion. The questions raised by Chen Heqian are all important links in the technique. And when Qin Hai answered, he also threw away the process and only mentioned the key concepts. This kind of dialogue between top experts does not review any principles, and often only one word is needed to make the other party understand their own thoughts, and the rest of the things only need to complement each other's brains.

"Teacher Chen, there are some things I don't understand." An assistant replied sneeringly, "However, I have already written down what you said to Teacher Qin just now. ”

Teacher Qin!

He was accompanied by an engineer from the missile unit, whose eyes widened wider than a brass bell when he heard the assistant's words. Chen Heqian is an approachable expert, but among the assistants around him are those who are above the top. This is the case with the person who spoke just now, during this time in the army, in addition to being honest in front of Chen Heqian, don't drag too much in front of the engineers in the army.

However, it is such a drag person, and he actually calls this childish young worker a teacher, and the 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 verification, he was not a person who could be a fake, and after being shocked by Qin Hai's knowledge, he forgot the fake identity that Yue Guoyang made up for him, and as soon as he spoke, he showed his feet.

Yue Guoyang desperately winked at Chen Heqian, and said in his mouth: "Old Chen, the level of our agricultural machinery technical school is still quite good, didn't you go?" ”

"Amazing, amazing." Chen Heqian muttered, "A student trained by an agricultural machinery technical school has such a strong theoretical foundation, talent, talent!" ”

"Teacher Chen has won the prize." Qin Hai hurriedly thanked Chen Heqian, he knew that what he said made Chen Heqian convinced, the reason for this was because he was an outstanding talent, and on the other hand, because he had knowledge decades ahead. Some of the content is not a great knowledge in the eyes of later generations of professionals, but in this era, it is a very avant-garde theoretical innovation.

"We've been talking all morning, are you hungry? Come on, let's put the table on the table, and everyone will talk while eating. Yue Guoyang stood up and greeted everyone.

Chen Heqian is a national-level expert, and Yue Guoyang has always respected him. Qin Hai was able to make Chen Heqian feel admired, and Yue Guoyang naturally regarded Qin Hai as an expert, and no longer treated him as a young worker. Seeing that the dialogue 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 a stain.

There are a few big trees on the edge of the lake, and according to Yue Guoyang's instructions, the dining table is arranged under this big tree, which is both shady and open, but it is in line with the tradition of soldiers.

Several guards brought a large round table from the cafeteria, set it up under the tree, and then began to distribute dishes and chopsticks. Zhu Chongwu led Qin Hai to the table, pointed out a seat for him, and said, "Xiao Qin, I see that Teacher Chen admires you very much, or you can sit next to Teacher Chen." ”

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

"Teacher Chen, please come here." Yue Guoyang also walked over with Chen Heqian, he pointed to Chen Heqian's seat, and said, "Teacher Chen, please sit here." ”

Chen Heqian walked to the table and was about to sit down, when his eyes inadvertently noticed the dishes and chopsticks placed in front of him, and he couldn't help but be stunned.

"Who gave me the chopsticks?" 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 dishes 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 hand for him, and then turned his head to look at Qin Hai on the side, his eyes flashing with suspicion.

Qin Hai smiled hehehe, stretched out his hand and gestured, "Teacher 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 moment just now.
