Rebirth of Military Workers

(Daughter-in-law’s book "The New Landlord of the Ming Dynasty" will be on the shelves today. The pace of the book is very slow and it is not suitable for net writing routines. Those who are interested can check it out. Anyway, she has been uploaded from June 10th to the present for four months. Time is up, this kind of persistence, for her, is already invaluable.)

Xie Kai didn't speak, looking at the people present, waiting for them to attack him.

As a result, after waiting for a while, the imaginary doubt did not appear.

The technicians, whose average age is at least 1.5 times his age, did not question his age.

"Comrade Xiao Xie, can you please introduce your armor model." A middle-aged man with a Chinese character face in his forties and wearing a Zhongshan suit stood up. Xie Kai thought he was finally about to take a trouble, but he said something like this. words.

He himself blushed at his stingy.

Since they all spoke on their own initiative, he was naturally not welcome. He picked up a chalk and drew an enlarged sketch model of the composite armor profile on the blackboard. Each layer was clearly divided and the name was written in words.

Then I pointed to the cross-sectional view on the blackboard, "Everyone, the Chobham armor developed by the British in the 1970s is a secret technology for us. Only some magazines and newspapers can see a vague introduction. According to the characteristics of this armor , I personally think that the theoretical model of this armor is made of high-hardness alloy steel plate + expansion reaction layer + carbon fiber layer + expanded ceramic layer + high-hardness alloy steel backing plate + aluminum-containing metal lining and other multi-layer structures, to tilt The corners are arranged, and the spaces between each layer are filled with special rubber or other refractory buffer materials..."

The layers of the cross-sectional view indicate what this layer is composed of.

This kind of thing is a model constructed through some technical information on the Internet plus some technologies involved in Xie Kai's usual military production.

Whether it has a huge protection ability, and did not conduct an experiment.

In any case, this theoretical model is definitely much more advanced than any kind of armor currently used in China.

"High-hardness alloy steel plate, what kind of alloy is used?" the middle-aged man with the face of Guozi asked at the beginning.

This question may seem simple, but in fact it is difficult to answer.

There are many types of high-hardness alloy steels. It is necessary to have a detailed understanding of the domestic and even international top alloy materials, and the material characteristics can be answered.

Seeing everyone staring at him, Xie Kai finally understood that it was not that they didn't question their age, or that they didn't make trouble.

Technicians' troubles will not be unreasonable at all, but will embarrass people with technology.

Once the answer is not good, his opinions will not be taken seriously in the future.

As long as you answer satisfactorily, you will never be questioned again in the future. Those who engage in technology are so innocent.

He is a technician himself, and he naturally knows their temper.

"Under the current situation, we can use a tungsten-nickel alloy with a nickel content of about 18%, and add some medium and heavy rare earth elements to the material to increase the strength..." As soon as Xie Kai opened his mouth, everyone's mouth opened wide. .

Those engaged in armor research are naturally very familiar with various materials.

The tungsten-nickel alloy mentioned by Xie Kai has been under development in China, and there is no mature technology yet.

Not to mention Xie Kai, many people who are engaged in materials do not necessarily know the tungsten-nickel alloy, especially the nickel content in it.

"Of course, if the tungsten-nickel alloy is not enough, it would be better to get the depleted uranium alloy researched by the United States."

"Comrade Xie Kai, it is difficult to make breakthroughs in depleted uranium alloys in the country in the short term, especially depleted uranium alloys have weak nuclear radiation, which is a threat to the health of soldiers who have been with tanks for a long time. Tungsten nickel alloys are high in strength and have not yet Mature application, and at the same time the production cost is very high..." It is still the middle-aged man.(Read more @ hotmtlnovel.xyz)

"The high cost makes large-scale equipment unrealistic." Another person said.

"At present, we are in an experimental state. The purpose of the project is not to consider cost, but to consider how to improve performance." Xie Kai said, "The cost is a large-scale equipment that must be considered. Now the production cost of tungsten nickel alloy is high because The technology is immature and the application field is not wide. Once it is used more, the cost will naturally come down."

The cost issue is also a very important factor in domestic weapon development and equipment.

The current shortage of military expenditures will continue for a long time.

"Tungsten-nickel alloy was originally used to make armor-piercing projectiles. Armour-piercing projectiles and armor of the same material. This is the problem of spears and shields." Someone asked again.

Faced with their constant troubles, Xie Kai was not only not upset, but he was relieved.

It's abnormal if you don't get into trouble.

"It is indeed the relationship between the spear and the shield. Whether the spear has stronger attack power or shield has stronger defensive power, it is relative, not absolute. In composite armor, this is only the outermost layer of defense." Xie Kai looked at the crowd and drew a circle on this layer of the blackboard with chalk.

“Installing high-hardness alloys on the outside mainly deals with high-explosive projectiles; while the use of multi-layer composite armor, whether it is high-explosive projectiles or armor-piercing projectiles, when the armor is hit, the high-strength alloy layer on the outside will affect the kinetic energy Perform maximum weakening...The other layers are responsible for further weakening the kinetic energy of the armor-piercing projectile and the power of the splash flow..." Xie Kai once again drew a shape that deforms when the armor is attacked.

Under the surprised eyes of everyone, they continued to point to the picture and introduce, "The expansion theory, this is the most proud achievement of Chobham. The composite armor is also produced by this theory. Everyone knows that the inclined armor layer will be attacked. , Will produce a certain degree of deformation, and decompose the horizontal force generated on the armor-piercing projectile into two horizontal and vertical forces."

Seeing everyone listening attentively, Xie Kai paused, and the organization language continued to introduce.

"In this way, we weaken our attack power while improving our own defense capabilities... Therefore, in the development process, we must consider that the outermost layer of high-strength alloy not only has high hardness, but also has higher toughness. ."

Such a theory is the most cutting-edge theory for current Republican armor researchers.

Such theories have been blocking China internationally.

Xie Kai has looked through many technical literature and magazines. The above mentions about Chobam armor, and seldom gives a detailed introduction to the theory of expansion reaction that led to the birth of Chobam armor.

"Anyone who knows the material knows that pure tungsten has high enough hardness and high brittleness; while nickel has good toughness. The alloys made of the two require higher hardness, so reduce the content of nickel... If you need higher toughness, increase nickel. The content. This requires experimentation."

The material structure formula, Xie Kai is also not very clear, and the material properties of different formulas are very different.

Previously engaged in technology and came into contact with various types of materials, even if he was asked to check it, it was difficult to find it.

The physical and chemical analysis data in the unit is confidential. Many materials in the military production unit are special materials, which are not available on the market.

"Before I saw an article about rare earth elements. There was a brief introduction to the properties of various elements. Adding a certain amount of rare earth elements can effectively increase the strength of metals... China is the world's largest rare earth element. Production and export countries have very little research on this aspect... Therefore, what kind of rare earth element or which types of rare earth elements are added can only be compared with experimental data..." Xie Kai clearly knows that adding rare earth elements such as scandium can improve The properties of the metal, but here, he can't say in more detail.

It can be known that the improvement of the properties of metals by rare earths is already very against the sky.

Especially his current age level.

Many people don't know what rare earths are for a lifetime.

"So, don't we need research materials?" Someone questioned.

They are only engaged in tank and armor.

"It can also be understood this way. If you don't even know the materials for tank armor, how can you do it?" Xie Kai said seriously. "In fact, we only need to conduct theoretical research, or even do not need to conduct theoretical research, as long as it feels feasible, we will use stupid methods-continuous trial production."

"In this way, the consumption of funds can be large." Zhang Deming said with a frown.

"We have our own materials laboratory, and the cost can be minimized. Each material only needs to be trial-produced in a small amount for research, and the cost is not high." Xie Kai replied, "Materials are the foundation of the foundation. During the development process , Even if the materials obtained cannot be used for armor, they can be used in other fields, and there is no waste."

Material is the foundation.

Everyone knows this. Many technical research fields are restricted because of the inability to obtain suitable materials.

The strength of the theoretically designed parts can be reached, but no material can be found to achieve this strength, which ultimately limits the development of technology.

"Pop! Papa! Papa..." The middle-aged man with Guozi face took the lead and applauded.

Others also reacted and clapped their hands.

Although there were only a dozen people, the applause was extremely loud.

"Old Cheng, he handed in this answer sheet to your satisfaction, right?" Zhang Deming asked the middle-aged man with the Chinese character face next to him.

Guozi looked at the blushing Xie Kai with a smile on his face, and nodded in satisfaction, "To be honest, I have been thinking about what he is like on the way here. When I saw him as a child, I even thought You are fooling around. But his introduction has subverted our understanding."

"How to subvert?" Zhang Deming asked with a grin.

"His understanding of the theoretical performance of various materials has even surpassed us. Even the judgment of some advanced cutting-edge materials is very accurate. Rare earth elements have improved the performance of metals. This is on our side and has just begun to make some breakthroughs... …" Cheng Ping sighed, "Sure enough, the waves behind the Yangtze River pushed the waves forward. We used to sit in the well and watch the sky."

"It's created by the environment. His dad has access to these technologies, coupled with the nature of their unit, and all kinds of the most advanced materials. The base is not as many children in the city outside, so he goes to the workshop to play when he has nothing to do. Or just read the various magazines his father borrowed at home, who would have thought he would be interested in a child? Unfortunately, my daughter is too young." Zhang Deming sighed.

"I can't wait to make the model he said for experimentation." Cheng Ping gave Zhang Deming a look at him. This guy was too shameless.
