Vol 2 Chapter 1751: Science

? Rotstoski looked at Yang Yang, slowly said: "So, what is the real useful chip for you? Is the basic material. [Full text reading]"
Gao Yang really does not understand this, he curiously said: "Basic materials?"
Roztoski nodded: "Yes, contact materials. For a country, especially an industrial country, basic materials are the most important, especially metal basic materials. This is the industrial foundation of a country. The high-end equipment manufacturing industry is the industrial crown of a country, but you have to have materials to make up this crown. "
Gao Yang nodded inexplicably, and Rostowski continued to laugh: "China has developed rapidly in recent years, and the research progress of gas turbines has not been slow. However, some key components still need to be imported from Ukraine. why?"
Gao Yang shook his head, indicating that he did not understand.
Lotztoski laughed: "Because of the lack of basic technology at certain key points, the basic materials industry requires a large investment, and long-term research can have some results. Having money to invest is one aspect, and more important, this requires Time, and people who do n’t know ca n’t see the results, think that this is a useless industry. Huaxia has developed rapidly in recent years. It stands to reason that Huaxia can use reverse engineering technology to make any complex equipment, such as These years have been troubled by the aviation engine developed by Huaxia, but why should Huaxia suffer from such a problem? "
Gao Yang whispered: "I really don't know how important the basic materials are, because I didn't understand it."
Lotztoski laughed: "I will give you an example. Once, I was ordered to obtain the key technology of an American engine. Finally, we got a turbofan engine and handed it to some of our institutions to reverse it. Research, at that time, the direction of technological development was already very clear. In the fighter plane, the turbojet engine will be replaced by the turbofan engine, so the engine I was ordered to bring back is highly valued. They copied the engine, but in the end Do you know the result? "
"What results?"
Rotztoski shook his head with a little helplessness: "They copied the engine perfectly, but. The power of the engine is two grades worse than the original, why? Because the rotor material of the turbo fan is not close, Because the blade material of the turbo fan is not strong enough to withstand ultra-high temperature and high pressure, the full power output will cause damage. While actively reducing the output power can barely be used, but the performance of the original product is two grades worse. "
Gao Yang nodded and said loudly: "It turned out to be this way, but since I got the real thing, wouldn't it be possible to do it based on the same material? Isn't metallographic analysis difficult? I don't understand this, don't laugh."
Several black devils all laughed.
Grevatov laughed: "It's not like this, it's not as simple as you think."
Lotztoski laughed: "Let me explain, this very high-end metal material, even if you get the real thing. And you can also analyze the specific ingredients, but even if you use the same material The same effect cannot be achieved. "
Roztoski beckoned to Grevatov: "Give me a piece of paper and a pen, and I will explain it to him."
After taking the paper and pen, Roztoski drew on the paper and smiled: "The same materials, different manufacturing processes, and different processes will have completely different performance. For example, I will give the simplest For example, a certain kind of steel contains iron. Nickel, chromium, tungsten, manganese, just these several materials, you get the real thing. You know the composition through analysis, but you do n’t know where the tungsten component should be When to add it, in short, the key casting part is to add all the materials together? Or when the basic material iron is 1,000 degrees Celsius, add nickel, and then add manganese at 1,200 Baidu, or the opposite What. "
Gao Yang said silly: "Is it critical?"
Rostowsky nodded: "Yes, it's critical, it's very critical. A small difference may lead to great differences in the properties of this material. There is no mistake in the research of basic materials, and failure in one direction It may mean success in the other direction. Sometimes, a material with superior performance may be just because of luck. It is really just luck that leads to the discovery and use of a completely new material. "
Gao Yang sighed: "It's complicated."
Rostowski laughed: "It's really complicated. This is a long-term investment, no output for a long time, and a lot of money. It's serious. Basic materials, especially high-end basic materials research is Burn money. "
Glevatov said lightly: "A certain material used in aircraft engines is at least dozens of alloys, and some components can only account for less than 1 in 10,000, but without this material, the performance is immediately inferior. No, so unless you can get all the production materials related to this material, it is possible to obtain materials with similar properties. As for the same, it is impossible, or better, or not as good as the original product. Why? Because it involves another A large area is the issue of manufacturing process level and the issue of purification process level, which involves a series of problems, which is very complicated ~ EbookFREE.me ~ Rotstosky laughed and said: "So, China is developing no matter how fast, Even if there is money, sometimes it is subject to some seemingly insignificant problems, because when it comes to high-end basic materials, you can only study slowly, try slowly, and experiment little by little. needs time. "
Glevatov said blankly: "Like the service life of the Soviet fighter engine is one thousand hours, and the engine life of the United States reaches more than 10,000 hours, this is a different understanding of war, and it is also about equipment The result of different use and research concepts, but if it can increase the service life without being too expensive, we certainly hope to extend the overhaul interval and increase the service life, but it is not possible, the material is not comparable to the United States, and the Soviet Union is using titanium In terms of alloys, it surpasses the United States. For example, using titanium alloys to make nuclear submarines, the United States is not as good as the Soviet Union. Is the United States less powerful than the Soviet Union? Is n’t American technology underdeveloped? No, they just have n’t found the right direction. That ’s enough, because they got a breakthrough. "
Gao Yang nodded again and again: "Thank you for your science, now I understand, that is to say, should I start in this respect?"
Rostowski nodded: "Yes, you should pay attention to this aspect, and you are very lucky, because I can tell you what is really good in Ukraine, especially the good things for you." Continued.)
