Qin Hai in this life did not know the person in front of him, but Qin Hai in the previous life was very familiar with him. 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 who was half dead. Qin Hai had worked with this man for more than half a year, and they met him many times at academic conferences. They were friends who had forgotten their years. This man was certainly not from the Provincial Military Region Repair Institute.
Engineer, but an academician of the Academy of Sciences and chief engineer of the Iron and Steel Institute, named Chen Heqian.
The Chen Heqian Qin Hai saw now was only about 40 years old and not an academician. However, Qin Hai knew that Chen Heqian had already made extraordinary achievements in the research on the properties of metal materials and was one of the big names in this field in China.
"It turns out to be Mr. Chen, I'm disrespectful."
Qin Hai didn't know why Chen Heqian was sitting here anonymously. Since Yue Guoyang didn't reveal his true identity, Qin Hai naturally couldn't expose it on the spot. If someone wanted to act with him, he would just act with him. He wanted to reminisce about the past.
There will be opportunities in the future. Also, can this be considered reminiscing about old times?
"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 tell me how this kind of steel is smelted?" Chen Heqian pushed.
The glasses on the bridge of his nose started to ask Qin Hai questions.
In fact, the real protagonist of today's scene is not Yue Guoyang, but Chen Heqian. The camp they are in is a missile force base in Anhe Province. Some time ago, the troops discovered the presence of tail fin materials of a certain type of missile during training
If there were any defects, local experts were invited to diagnose them. It was for this reason that Chen Heqian came here.
Yesterday, after Yue Guoyang received the dagger and engineering shovel sent by Ge Dongyan, he had been thinking about how to solve the steel problem. He knew that the experts from the Iron and Steel Institute were in the missile force in the suburbs of Hongze, so he came over in person to take these two pieces.
The product was sent to Chen Heqian for appraisal.
Chen Heqian was shocked when he saw these two things. He asked his assistants to use instruments to test the steel, and concluded that the strength of this steel exceeded the strength of the best alloy steel currently available in the country, especially
Its high-temperature resistance is even more outstanding. Although this kind of steel cannot be directly used to manufacture missile tails, using the ideas of this kind of steel can easily solve the current dilemma they are facing.
As soon as this conclusion came out, Yue Guoyang was also stunned. Chen Heqian and others had been busy at 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 was simply too dramatic. Chen Heqian
He immediately requested to meet with the inventor of this steel. 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
Go to Qingfeng Agricultural Machinery Factory and discuss the transfer of Qin Hai to the Provincial Military Region to assist in the work.
Naturally, Qin Hai didn't know about these situations. However, when he recognized Chen Heqian, he knew that Yue Guoyang had called him here not just for an engineering shovel. The project that would allow Chen Heqian to come forward was definitely not simple.
After understanding this section, Qin Hai was too lazy to play any more tricks. It was just a formula for ultra-high-strength steel. Even if it was a meeting gift for an old friend, it didn't matter. He smiled slightly and said: "Mr. Chen,
In fact, the steel I make is not a new process. I just imitated the smelting ideas of H11 and H13, two types of heat-deformed die steel, and used secondary hardening to increase the strength of the alloy steel."
"But the strength of steel like yours is obviously higher than 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 reduced?"
"This is achieved by adding an appropriate amount of nickel, which can also improve the hardenability of steel."
"How do you design the heat treatment process?"
"Air cooling at 1010 degrees Celsius and tempering at 550 degrees Celsius can form a lath martensite structure with high dislocation density under air cooling conditions..."
"...Are you really a graduate of the Agricultural Machinery Technical School?" Chen Heqian looked at Qin Hai with horrified eyes, and the various expressions on his face were intertwined, making it indescribable.
"Uh...did I say a little too much?" Qin Hai said with a bitter smile.
When answering questions just now, Qin Hai had long forgotten his time-travel identity and seemed to be back before time-travel. At that time, he would always ask and answer questions like this every time he was with Chen Heqian, and his thoughts jumped so fast that the people listening
They couldn't even react. However, at that time, Qin Hai was a postdoctoral fellow at the Institute of Materials Science and had the ability to talk to Chen Heqian. Now this Qin Hai is just a technical school student, and what he said made even the chief engineer of the Iron and Steel Institute find it incredible.
This is simply a monster!
"Do you understand?" Chen Heqian turned his head to the people next to him and asked.
Next to him were several assistants brought by Chen Heqian on this trip, including graduate students and assistant engineers who were already working. During the conversation between Chen Heqian and Qin Hai, they were able to grasp some concepts at first, but they soon became completely confused.
I fell into confusion. The questions raised by Chen Heqian were all important aspects of technology. When Qin Hai answered, he also ignored the process and only mentioned key concepts. Such conversations between top experts would not be reviewed.
What's the principle? It often only takes one word to make the other party understand what you are thinking, and the rest just needs to be figured out by each other.
"Teacher Chen, there are some things I didn't understand." An assistant replied calmly, "But I have already written down what you and Teacher Qin just said."
Teacher Qin!
Accompanying him were engineers from the missile force. When he heard the assistant's words, his eyes were bigger than bells. Chen Heqian was an approachable expert, but among the assistants around him, there were people who had higher eyesight. Just now
The person who spoke is like this. During the time he came to the army, in addition to being more honest in front of Chen Heqian, he should not be too arrogant in front of the engineers in the army.
However, he is such a drag and actually calls this childish young worker a teacher. This world is really hard to understand.
"Commander Yue, the level of your technical school is so high?" Chen Heqian turned to Yue Guoyang for confirmation. He was not a person who could falsify. After being shocked by Qin Hai's knowledge, he even forgot about the one Yue Guoyang made up for him.
His fake identity is revealed as soon as he speaks.
Yue Guoyang blinked desperately at Chen Heqian and said, "Old Chen, the level of our Agricultural Machinery Technical School is quite good. You didn't go, did you?"
"It's amazing, it's amazing." Chen Heqian murmured, "A student trained in an agricultural machinery technical school actually has such a strong theoretical foundation. Talent, talent!"
"Teacher Chen, thank you." Qin Hai quickly thanked Chen Heqian. He knew that Chen Heqian was convinced by what he said. The reason for this was, on the one hand, that he was an outstanding talent, and on the other hand, because
He possesses knowledge that is decades ahead of his time. Some of the contents may not be regarded as great knowledge by later generations of professionals, but in this era, they are considered very avant-garde theoretical innovations.
"We've been chatting all morning, are you hungry? Come on, let's set the table and let's chat while we eat." Yue Guoyang stood up and greeted everyone.
Chen Heqian is a national-level expert, and Yue Guoyang has always respected him. Qin Hai can admire Chen Heqian, and Yue Guoyang naturally regards Qin Hai as an expert and no longer treats him as a young worker. See.
When the conversation between the two parties 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 taking advantage of it.
There are several tall trees with pavilions like canopies on the edge of the lake. According to Yue Guoyang's instructions, the dining table was arranged under these big trees. This way, it is shaded and open, which is in line with the tradition of the military.
Several guardsmen brought a large round table from the canteen, set it up under the tree, and then began to distribute bowls and chopsticks. Zhu Chongwu led Qin Hai to the table, pointed him to a seat, and said: "Xiao Qin, let me see
Teacher Chen appreciates you very much, how about you sit next to Teacher Chen."
"No problem." Qin Hai nodded, then walked forward and moved the bowls and chopsticks next to his seat slightly.
"Teacher Chen, please come over here." Yue Guoyang came over accompanied by 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 accidentally noticed the bowls and chopsticks placed in front of him and he couldn't help but be startled.
"Who set these chopsticks for me?" Chen Heqian asked.
"It's Comrade Qin." The guard soldier who was serving next to him said. He looked at the position of the bowls and chopsticks and couldn't help but muttered: "This Comrade Qin is really the same. Why did you put your chopsticks on the left hand side...
"
"Don't move!" Chen Heqian stopped the guard who was about to move the chopsticks to his right side for him, then turned to look at Qin Hai beside him, with suspicion in his eyes.
Qin Hai chuckled, stretched out his hand and said, "Teacher 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 no less shocked at this moment than he was just now.
