Material Empire

Ji Mingchu said that he has retired, which is true. But to say that he is just an ordinary citizen would be a big joke. As one of the few remaining founding fathers, Ji Mingchu had a very high status in the military and the central government, and was able to participate in various major decision-making. Since he had retired from the front line, there were very few chances for his name and photo to be published in the newspapers, which was why Qin Hai couldn't recognize him.

Qin Hai remembers that Ji Mingchu died a few years before he traveled, and the photos published in the media at that time were much older than now. In the current Ji Mingchu, although his hair is more than half gray and there are several age spots on his face, he is a tiger, whether he is standing or sitting, he can give people a great sense of psychological oppression.

Mr. Ji, I'm so sorry, I didn't recognize you. Qin Hai quickly apologized. Even if he had never met Ji Mingchu before, at least some epic dramas still have the image of Ji Mingchu. The difference from the real person in front of him is not too far, so Qin Hai should be able to guess his identity.

It's not a mistake not to know me. There's nothing to be embarrassed about. Ji Mingchu waved his hand and said, You know who I am now. I asked you the question just now. You can think about it again, whether it can be done.

Yes! Qin Hai gave a resounding answer without even stuttering.

Haha, so happy? Ji Mingchu laughed. Just the word capable made Ji Mingchu feel good about Qin Hai. As an old general who came out of the bloody storm, he likes responsible young people very much. Qin Hai's performance was in line with his temper.

Mr. Ji, your request must be related to national defense. As long as you can make it, we have no reason to refuse. Qin Hai said solemnly.

At this time, Qin Hai was also unable to get off the tiger. Ji Mingchu made a request to him in front of so many people, especially if there was a chief at the scene, even if someone borrowed Qin Hai's courage, he would not dare to directly refuse Ji Mingchu. At this moment, he can only bite the bullet and agree to any request that Ji Mingchu may make. If some of the requests are beyond his ability, he will have to wait until later and slowly shirk them.

Of course, from another point of view, Qin Hai also believes that Ji Mingchu is not the kind of person who is aimless. The demands he can make should be within a reasonable range, and they must be topics that are highly related to national defense construction. Qin Hai cared about national defense technology in the first place, how could he refuse such a request?

Ji Mingchu nodded, and then said: Xiao Qin, I heard from the teacher that you have very good attainments in materials and are familiar with the laws of the materials industry, so I can't ask others for this matter, I can only ask you.

Mr. Ji, please tell me. Qin Hai was not modest this time, and accepted Ji Mingchu's compliment frankly.

Ji Mingchu said: Do you know the No. 98 steel?

No. 98 steel? Qin Hai's eyes lit up, and it turned out that what Ji Mingchu had in mind was such a thing.

In his previous life, Qin Hai, as an interdisciplinary material expert, was involved in many important military projects. It was at that time that he knew what No. 98 steel was, and he also had a deep understanding of the research and development process of this steel. impression. The so-called No. 98 steel is actually a number determined internally by the military. Coincidentally, when Qin Hai and Wang Hongsheng discussed holding a material science and technology exhibition, Qin Hai also gave an example of this kind of steel. It is used on aircraft carriers. special deck steel.

The ship plate steel used by warships is different from that of ordinary civilian ships. The ship plate steel for civilian ships only needs to be considered strong, durable, especially resistant to seawater corrosion. Warship steel needs to add special requirements such as impact resistance and high temperature resistance. Simply put, it is to ensure a certain survivability in a war environment. Much higher.

Among all military ship plate steels, the steel requirements for manufacturing aircraft carrier decks and nuclear submarine pressure hulls are the most stringent. In peacetime, the chances of warships encountering missile strikes are very small, and generally speaking, as long as they can withstand one or two strikes, it is enough to meet the protection requirements. However, aircraft carrier deck steel and nuclear submarine pressure hull steel are different. They need to work in harsh environments for a long time, and there is almost no difference between peacetime and wartime.

Take aircraft carrier deck steel as an example. The deck is used for carrier-based aircraft to take off and land. When the aircraft takes off, the flames from the engine will cause high temperature and scorching heat on the deck; when the aircraft lands, the landing gear will have a huge impact on the deck. That is to say, the deck of an aircraft carrier is subjected to repeated attacks almost every day. In this case, it must be ensured that it does not deform, otherwise it will have a serious impact on aircraft take-off and landing.

A simple performance index can explain the high requirements of deck steel. The yield strength of ordinary civilian ship plate steel is about 250 MPa. For the ship plate steel of ordinary military ships, the yield strength is required to reach 350 MPa. The aircraft carrier deck steel used in the United States, including HY130 and HSLA-115, has a yield strength of more than 800 MPa.

Here is a simple popularization of science: 1 MPa means that it bears a pressure of 1 million Newtons per square meter. What people usually say is that 1 atmosphere is only equivalent to 0.1 MPa. 800 MPa means being able to withstand... well, a lot of pressure anyway.

At that time, the maximum yield strength of ship plate steel that could be produced in China could only reach 440 MPa. Compared with the ship plate steel with yield strength of more than 1000 MPa owned by the United States, the Soviet Union, Japan, and France, the gap was still very obvious. .

The development of No. 98 steel is to solve the bottleneck of ultra-high-strength ship plate steel and provide a material basis for the construction of China's aircraft carriers and nuclear submarines. However, due to insufficient technology accumulation and limited national investment, the development of No. 98 steel is currently in a difficult situation.

Ji Mingchu is a representative of the hawks in the army, and he has a deep affection for both aircraft carriers and submarines. This time, he accompanied the chief to visit the material exhibition, and listened to the planning committee's development ideas on material technology. With a thought, he brought the issue of No. 98 steel to Qin Hai. In his heart, there is a faint expectation that maybe this young man can make the development of No. 98 steel come to fruition.

In this life, because of his relationship with Chen Heqian, Qin Hai had heard the name No. 98 steel, so when Ji Mingchu mentioned No. 98 steel, Qin Hai didn't have to pretend to be ignorant of it. He nodded slightly, and said, Old Ji, I heard Professor Chen mention the No. 98 steel.

If I entrust this matter to you, can you get it out? Ji Mingchu is worthy of being a soldier, and he doesn't talk around corners at all.

Qin Hai turned his head to look at the people in the VIP room, and smiled without saying a word. He knew that apart from himself, the young organizer of the exhibition, those who could participate in this discussion were at least officials above the deputy ministerial level, and there was no need to keep secrets at the level of No. 98 steel. Even so, Qin Hai didn't want to discuss this topic in front of everyone, because he still had some conditions to talk to the old general, and if there were too many people, he would have nothing to say.

Haha, I understand. No one in Ji Mingchu could guess the little calculations in Qin Hai's stomach. In his opinion, Qin Hai's willingness to have a secret talk with him is actually a good thing. This shows that Qin Hai is interested in this matter and also has a certain degree of certainty. This is better than slapping his chest loudly in front of everyone. too much.

The distraction at the beginning of the Ming Dynasty passed in this way, and the chief then issued a series of instructions for this material exhibition. Naturally, Wang Hongsheng and others hurriedly took out their small notebooks and wrote them down one by one, so that they can be implemented item by item in the future, and organize their own units. of people deep learning. The leaders' speeches are not necessarily all the truth, but these speeches all contain the leaders' views or expectations on a certain matter. As a subordinate, it is very important to understand the leader's intention. If you do something that is contrary to the leader's idea, no matter how good you are, it will be difficult to get praise.

At the end of the discussion, the chief got up and left, but Ji Mingchu stayed behind. Wang Hongsheng knew that he and Qin Hai had something to say, so he arranged for someone to take the two of them into a smaller room. After the staff poured tea for the two of them, they left obediently, and closed the door carefully after going out.

Okay, now there is no one else, why don't you tell me what you think? Ji Mingchu took out a cigarette from his pocket and lit it, took a good puff, and then said to Qin Hai.

Qin Hai sat upright on the sofa, showing a respectful gesture. Regarding Ji Mingchu's behavior of smoking a single cigarette, he dare not have any complaints. After all, his status is far from that of Ji Mingchu, and so far he has not done anything enough to make Ji Mingchu pay respect to him. If it was Yang Xinyu, Wang Hongsheng and others in front of them, even if they knew that Qin Hai didn't smoke, they would give way to them symbolically.

Mr. Ji, I want to know how the current research progress of No. 98 steel is going. Qin Hai said.

Ji Mingchu admired Qin Hai's performance quite a bit. A young man in his early 20s, with no job or power, could calmly stand in front of him and speak without any confusion. This fully demonstrated that this young man has a lot of Strong self-confidence and good psychological quality. Such a person is like a person who can take on heavy responsibilities.

Ming people don't say dark words, and the current progress is very slow. Researchers are stuck at the level of No. 95 steel, and it is difficult to move forward. It has been six or seven years since No. 95 steel was successfully developed. We can’t see the day when Steel No. 98 was born.” Ji Mingchu said.

Mr. Ji, you don't have to say that. Your body is stronger than mine. I think you can live for another 20 or 30 years without saying anything. Don't worry, you will definitely see the birth of No. 98 steel in your lifetime. Qin Hai smiled and said an auspicious word. The old man is already 80 years old this year, and living another 20 or 30 years is considered a long life, so this kind of prophecy should be regarded as a blessing rather than a curse.

Let me just say that the old general was only made up for the needs of the plot. There is no prototype, and he doesn't try to refer to anyone, so don't guess. It is especially emphasized that this book is only an industrial document.
