Material Empire

It is true that Ji Mingchu said that he had retired. But to say that he is just an ordinary people, that is a big joke. As one of the first founding fathers to have achieved great results, Ji Ming had a very high position in the military and the central government and was able to participate in various major decisions. Since he has already withdrawn from the front line, his chances of appearing in the newspapers with his name and photos are rare, which is why Qin Hai did not recognize him.

Qin Hai remembers that he died early in the Ming and Ming dynasties a few years before his crossing, when the photos published in the media were much older than they are now. Now in the early days of Ji Ming, although the hair has been more than half white and several age spots have appeared on the face, the old tiger is still in the air. Whether it is sitting or standing, it can give people a great sense of psychological oppression.

"Ji old, I'm sorry, I didn't recognize you." Qin Hai hastened to apologize, even if he hasn't seen Ji Ming early, at least some epic dramas still have the image of Ji Ming early. It is not too far away from the real person in front of him, so Qin Hai should be able to guess his identity.

"It's not a mistake not to know me, and there's nothing to be embarrassed about." Ji Mingchu waved his hands and said, "You now know who I am. I asked your question just now. You can think about it again and see if it can be done."

"Yes!" Qin Hai didn't even hit a bus at this time, and gave a loud answer directly.

"Haha, so happy?" Ji Ming smiled at the beginning. The word "can" just made Ji Haidun feel good about Qin Haidun at the beginning of Ming and Ming Dynasty, as an old general coming out of the **** storm. He likes young people with responsibility. Qin Hai's performance was right for his temper.

"Ji Lao, your request. It must be related to the national defense plan. As long as you can make it, we have no reason to reject it." Qin Hai said rightly.

At this time, Qin Hai was also difficult to ride a tiger. In the early days of Ji Ming, so many people made demands to him, especially the head of the scene. Even if he borrowed some courage from Qin Hai, he did not dare to directly reject the early Ming Dynasty. At this time, he could only brazenly agree to any request that might be made in the early Ming Dynasty. If any of these requirements are beyond his capabilities, he will have to wait until later.

of course. From another perspective, Qin Hai also believed that Ji Mingchu was not the kind of untargeted person. The requirements he could put forward should be within a reasonable range. It must also be a subject highly related to national defense construction. Qin Hai was concerned about national defense technology. How could he refuse such a request?

Ji Ming nodded at the beginning, and then said, "Xiao Qin, I heard Shi Lao said that your accomplishments in materials are very good, and you are familiar with the laws of the material industry, so I cannot trust others in this matter, I can only trust you."

"Ji Lao, please speak." Qin Hai was not modest this time, and frankly accepted the praise of Ji Ming early.

Early in the Ming Dynasty said: "Do you know No. 98 steel?"

"No. 98 steel?" Qin Hai lighted up. It turned out that this was the thing that Ji Ming thought at the beginning.

As an interdisciplinary material expert, Qin Hai of the previous life was involved in many important military projects. It was also at that time that he knew what was No. 98 steel, and he was very impressed with the development process of this steel. The so-called No. 98 steel is actually a number determined internally by the military. It is also a coincidence that when Qin Hai and Wang Hongsheng discussed holding a material technology exhibition, Qin Hai also cited examples of this kind of steel. It is the special deck steel used on aircraft carriers.

Ships use different steel plates from ordinary civilian ships. The plate steel of civil ships only needs to be considered strong and durable, especially resistant to seawater corrosion. Warship steel needs special requirements such as impact resistance and high temperature resistance. To put it simply, it is necessary to ensure a certain viability in a war environment. In this sense, the requirements of steel plates for warships are much higher than those for civil ships.

Of all the steel plates used for military ships, the steel required for the manufacture of carrier decks and nuclear submarine pressure shells is the most stringent. In peacetime, the chances of warships being hit by missiles are very small, and in general, as long as they can withstand one or two strikes, they are enough to meet the protection requirements. However, aircraft carrier deck steel and nuclear submarine pressure-resistant shell steel are different. They need to work under harsh environments for a long time, and there is almost no difference between peace and war.

Take aircraft carrier deck steel. The deck is used for carrier-based aircraft take-off and landing. When the aircraft takes off, the flames emitted by the engine will cause high-temperature burning of the deck; when the aircraft lands, the landing gear will have a huge impact on the deck. That is to say, the aircraft carrier deck 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 the takeoff and landing of the aircraft.

A simple performance index can explain the high requirements of deck steel. The ordinary civil ship steel has a yield strength of about 250 MPa. The plate strength of ordinary military ships is required to reach 350 MPa. The aircraft carrier deck steels used in the United States, including hy130 and hsla-115, have yield strengths exceeding 800 MPa.

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

In that era, the maximum yield strength of ship plate steel that China could produce could only reach 440 MPa, compared with ship plate steels with yield strengths exceeding 1,000 MPa owned by the United States, the Soviet Union, Japan, and France. .

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 aircraft carriers and nuclear submarines in China. However, due to insufficient technology accumulation and limited national investment, the development of 98 steel is currently in a difficult position.

Early in the Ming Dynasty, he was a hawk representative in the army, and he had a deep feeling for aircraft carriers and submarines. This time, I accompanied the director to visit the material exhibition, and heard about the development ideas of material science and technology from the Planning Commission. With a thought, he brought the issue of steel No. 98 to Qin Hai. In his mind, there was a faint expectation that perhaps this young man could let the development of No. 98 steel shine.

In this life, because of his relationship with Chen Heqian, Qin Hai once heard the name of steel No. 98, so when Ji Ming raised the steel of No. 98 in the early Ming Dynasty, Qin Hai didn't need to pretend that he didn't know it. He nodded slightly and said, "Ji Lao, I heard Professor Chen mentioned Steel No. 98."

"If I leave it to you to do it, can you get it out?" Ji Mingchu was indeed a famous soldier, and he didn't go round the corner at all.

Qin Hai turned to look at the people in the VIP room and smiled. He knew that, except for the young exhibition organizer himself, who was able to participate in the symposium, at least the officials above the deputy ministerial level and the confidentiality of steel No. 98 did not need to be kept secret. 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 veteran general. There were no more people to talk about.

"Haha, I see." He Xuren at the beginning of the Ming Dynasty could not guess the little abacus in Qin Hai's belly. In his opinion, Qin Hai was willing to talk to him in secret, but it was a good thing, which showed that Qin Hai was both interested and certain in this matter, which was stronger than slap the chest in front of everyone. too much.

The fork that broke in the early period of Ji Ming passed like this, and the director then gave a series of instructions to this material exhibition. Wang Hongsheng and others naturally hurriedly took out small books one by one in order to implement them one by one in the future and organize the unit. Of people "deep learning." Leadership speeches are not necessarily truth, but these speeches contain leaders' views or expectations on something. As a subordinate, it is very important to understand the intention of the leader. If you run counter to the idea of ​​the leader, it is hard to get praise for doing so well.

After the discussion, the heads got up and left, but they stayed in the early Ming Dynasty. Wang Hongsheng knew that he and Qin Hai had something to say, so he arranged for someone to take them to a smaller room. After the staff poured tea for the two of them, they left nicely and closed the door carefully after going out.

"Well, now there are no more people, can you tell me what you think?" Ji Mingchu took out a cigarette from his pocket and took a sip, then said to Qin Hai.

Qin Hai sat upright on the sofa and made a respectful gesture. He dared not have any complaints about smoking alone in Ji Mingchu. After all, his status is far from that of Ji Mingchu, and so far he has not done enough to make him pay respect to him. If they replaced Yang Xinyu, Wang Hongsheng, etc. in front of them, they would symbolically be polite even if they knew that Qin Hai would not smoke.

"Ji Lao ~ www.novelmtl.com ~ I want to know how the current research progress of No. 98 steel is." Qin Hai said.

At the beginning of the Ming Dynasty, he was quite appreciative of Qin Hai's performance. A young man in his early 20s had no job and power. He was calm and calm in front of him, and there was no confusion in the logic of speaking. This fully shows that this young man has a very Strong self-confidence and good mental quality. Such a person is like someone who can take on heavy responsibility.

"Mingren don't talk secretly, the progress is very slow now. Researchers are stuck at the level of steel 95, it is difficult to move forward. It has been six or seven years since the successful development of steel 95, and I am worried about me. I can't see the day when No. 98 steel was born. "Ji Mingchu said.

"Ji Lao doesn't have to say this. You are physically stronger than me. I don't think you can live another 20 to 30 years. You can rest assured that in your lifetime, you will be able to see the birth of No. 98 steel." Qin Hai Xiaohe said something auspicious. The old man is already 80 years old this year, and how long to live another two or three decades can be considered longevity, so this prediction should be regarded as a blessing instead of a curse.
