Reborn superpower

() "Xiao Zhao, come, let's eat some food." The chief immediately reminded him when he sensed the change in Zao Wou-ki.

"Hehe, I'm sorry. I should learn more about raising Qi from the chief!" Zhao Wuji scratched his head, who is the chief, and he can be mad in front of him.A few years ago, when the head of state was negotiating with the prime minister of Britain, that was power!

No one in the outside world knew about this secret conversation.But after this secret talk, Huaxia's style changed and became more pragmatic.There are some institutional changes, which are at least three to five years ahead of the parallel time and space.

Of course, it will take a few years to finally change the history of China, or China's real rapid development.

However, compared with the previous life, Zao Wou-ki's current life not only expands faster in quantity and scale, but also has better and higher quality.In some key areas of the national economy, such as biotechnology, computer technology, the Internet, etc., it is enough to be ahead of the Western generation in technology.And our previous shortcomings, such as industrial mother machines and special materials, have also surpassed the West as a whole.Duplicated construction, disparity between rich and poor, and interest groups, etc., also exist, but they are much better than parallel time and space.

Governing a country is difficult. Even in the West, it is full of interest groups and various complex social contradictions.

……

This night, although the leader was very talkative, Zao Wou-ki left at 10 pm.As for where to live, the Huaxia Academy of Sciences booked a room for him, because the next day he will participate in the "Report on New Technology Achievements of Special Materials and Special Alloys" hosted by the Ministry of Science and Technology, the Chinese Academy of Sciences, and the Academy of Engineering.

Huaxia has always had a large scientific research team conducting research on special materials and special alloys. However, due to the low starting point and years of isolation from the world, the research progress is not ideal.At least not directly proportional between input and output.

someone said.Huaxia does not attach importance to scientific and technological research.This depends on which angle you look at it, such as special materials and special alloys, which are related to military industry, missiles, nuclear weapons and other industries.How could it be ignored?If you don't pay attention to it, you may really not pay much attention to basic science.

[-], also known as the Institute of Engineering Physics, is one of the most important research institutes under the national defense system and one of the most important supporting research institutions for China's "two bombs and one satellite".

therefore.After Zao Wou-ki saw Chen Dashan holding a monograph on materials science in his Zizhou bookstore, he immediately seized the opportunity and "sold" himself, thus opening up another world for Zao Wou-ki.

Special material is a composite concept. From the perspective of functional characteristics, it can be divided into high temperature resistant materials, low temperature resistant materials, acid resistant materials, alkali resistant materials, wear resistance, high speed resistance, bending and distortion resistance, Anti-aging materials, etc. In addition, there are energetic materials (such as explosives)... From the perspective of material composition, there are non-metallic materials, metallic materials, synthetic materials, polymer materials, and so on.

Zao Wou-ki led the [-] research team's main research direction, and initially only chose two.One is high-temperature resistant materials, that is, high-performance refractory materials or special refractory materials; the other is special alloys.

Hereafter.In this regard, China cannot be said to be too backward.But compared with Mi, Xiong, and Pu, we have never been able to manufacture engines comparable to them, and they are always inferior. We are called a late generation technically. The important reason is that our refractory materials are not good. The flight speed of our rockets and missiles is much lower than that of the opponent, because the engine is not resistant to high temperature, the energy burned within the same period of time is limited, and the thrust produced is limited.

Special refractory materials also include a wide range of contents, mainly including high melting point oxides, high melting point non-oxides and composite compounds derived therefrom, cermets, high temperature coatings, high temperature fibers and their reinforcing materials.Among them, high melting point non-oxides are usually called refractory compounds, which include carbides, nitrides, borides, silicides and sulfides.

Zao Wou-ki’s research this time mainly focuses on the three types of carbides, nitrides, and silicides in high-melting non-oxides. After several months of repeated research and experiments, he finally achieved "the overall level is equal to the world's advanced level and some parts are ahead of the world." "Technical breakthrough.

The use of special materials is also very mysterious and magical. For example, high-temperature coating, as long as such a layer is applied, the life of the engine boiler can be doubled, and its high temperature resistance can be increased by hundreds or even thousands of degrees. .

For example, our rockets originally could only fly at a speed of 3000 kilometers per hour, but after using the latest high-temperature-resistant coating materials, they can suddenly increase to 3500 kilometers or even more than 4000 kilometers.

Special metal materials have developed into a huge family in later generations, such as amorphous metal materials obtained through rapid condensation technology, and quasicrystalline, microcrystalline, and nanocrystalline metal materials; in addition, there are stealth, hydrogen-resistant , superconducting, shape memory, wear-resistant, damping and vibration reduction and other special functional alloys, as well as metal matrix composite materials, etc.

In the field of special alloy research, Zao Wou-ki also did not seek too much, he only chose a kind of "cermet" for research.In terms of subject classification, cermets belong to the following category of "composite materials of high melting point oxides and refractory metals".However, this kind of "cermet" has a wide range of uses in the field of modern production.

There are quite a lot of classifications of cermets, and Zao Wou-ki led the research on three materials:

The first is "oxide-based cermets". This kind of ceramics has the characteristics of high temperature resistance, pouring corrosion resistance, good thermal conductivity, and high mechanical strength. It can be used for missile nozzle bushings, crucibles for melting metals, and metal cutting tools.

The second type is called "carbide-based cermets", which have the characteristics of high hardness, high wear resistance, and high temperature resistance, and are used in the manufacture of cutting tools, high temperature bearings, sealing rings, wire picking mold sets and turbine blades.

The third type belongs to "metal-based cermet", which is made by adding oxide fine powder to the metal matrix, also known as dispersion reinforced material, such as a material called "sintered aluminum". Compared with alloy aluminum, its high temperature strength is high, Small density, easy processing, corrosion resistance, good thermal conductivity.It is often used in the manufacture of structural parts of aircraft and missiles, engine pistons, chemical machinery parts, etc.

From the uses of these three "cermets", it is not difficult to see the significance of Zao Wou-ki's "breakthrough" in choosing these research projects.Nigerian media, it is these things that are not good enough, and China has been controlled by others for a long time.

If it was his previous life, Zao Wou-ki would have a headache when he saw these technical terms. For example, the "damping and vibration reduction" is no less difficult for liberal arts students than Einstein's theory of relativity.

In fact, it is easy to understand the four words "damping and vibration reduction": "When a solid vibrates, the method of dissipating the energy of the solid vibration in the damping layer as much as possible is called damping and vibration reduction. "And "damping" refers to an effect that hinders the relative motion of objects and converts motion energy into heat energy or other energy that can be dissipated (? Star liberal arts students, don't spray).

There is an online novel in later generations, which also writes about using ceramics to make car engines. In fact, the word "metal" is missing in that book.Because only ceramics have the characteristics of high temperature resistance, corrosion resistance and wear resistance, but lack the toughness, high thermal conductivity and good thermal stability of metals. Obviously, automobile engines must be made of "metal" and "ceramic". "The combination of "metal ceramics" is the best.

Things that lack toughness are fragile, and it seems that car engines will not only use ceramics as an ingredient.Of course, that's just a novel, and how to write it is the author's free will.Perhaps, that thing really exists, but Zhao Wuji has not touched it yet.

The "Report on New Technology Achievements of Special Materials and Special Alloys" was held on the afternoon of the 13th, and Zao Wou-ki had nothing to do in the morning.

Because Zao Wou-ki is the "Chief Scientist" of this research, in the morning, the Academy of Engineering sent a researcher (deputy director) named Ye Hai from the Institute of Metal Materials to ask for Zao Wou-ki's opinions on arranging the report meeting.

Zao Wou-ki paid high tribute to this grizzled scientist who was in his early 50s and had worked in the Institute of Metal Materials of the Academy of Engineering for 30 years.

There are many "bricks" in their early 50s in later generations. Isn't it a good time to give speeches during the day and wash your feet in the bath at night?It's just that these scientists who have worked in obscurity for the country all their lives, when they have a footwashing room and a sauna room, they are already too old to walk.

Zao Wou-ki suddenly remembered that his "promise" from the head, to those so-called politicians, only 12 places for maintenance and treatment a year, and 120 places without a brain impulse, it is too "wise"; Because, from Ye Hai, he saw the greater value of his miraculous medical skills, which is to try his best to save the life of these older generation of scientists.

If these scientists can live for five more years, their contribution to China will be unparalleled, because many scientists are exhausted and their lives are no longer just when they are about to produce results.But for those so-called politicians, if they live five years longer, they will consume more social wealth.

Of course, there are some politicians who have their nation and country in their hearts, such people are naturally worth taking action; but at least half of them, Zao Wou-ki feels that they are superfluous people living in this world.

However, Zao Wou-ki hadn't figured out how to deal with this matter yet, Ye Hai talked about a piece of news that almost scared Zhao Wou-ki into having a heart attack.

It turned out that this briefing will invite news organizations to participate, and at the same time, according to the instructions of the Hua Xuan Department, Zhao Wuji will be interviewed at the briefing, and the results obtained in these briefings will be reported on major national media.

"Are you going to prepare a press release or a document introducing the results?" Zhao Wou-ki asked calmly although he almost had a heart attack.

"Yes. Academician Zhao please take a look." Ye Hai took out a stack of materials.

It only took Zao Wou-ki 5 minutes to finish reading more than a dozen pages of materials prepared for the reporter. If it wasn't for fear of arousing Ye Hai's suspicion, Zao Wou-ki would be able to know the general content at a glance.

"I don't agree with this press conference!" After reading the material, Zhao Wou-ki pointed to the material and said seriously. (To be continued.)
