Ordinary metals are smelted directly in a steelmaking furnace, then cast into steel ingots, and then become what they need through a series of rolling, cutting, etc.
Powder metallurgy is refining. It is a process technology that produces metal powders or uses metal powders, which can also include mixtures of non-metal powders as raw materials, and is formed and sintered to produce metal materials, composite materials and various types of products.
Powder metallurgy is similar to the production of ceramics, and both belong to powder sintering technology. This powder metallurgy technology is a key production method in materials science and plays an important role in the development of new materials.
After hearing what Mr. Zhu said, Qin Zhenhua immediately thought of armor-piercing bombs. In terms of developing armor-piercing bombs, the first machine factory has always had the strongest strength. Qin Zhenhua has long started to use tungsten alloy to manufacture it, and its performance has been greatly improved.
.
However, Qin Zhenhua is still using the most ordinary tungsten alloy. The warhead cut through machine tools is not only a waste problem, but also it is impossible to further increase the potential.
If the bullet has a stronger armor-piercing ability, it is necessary to have a denser tungsten alloy and a stronger tungsten alloy. This tungsten alloy can directly become the core of the armor-piercing bomb after being sintered directly through the powder.
At most, apply a knife to the lathe and make sure it is done.
The greater the density, the stronger the armor-piercing ability, the higher the strength, the greater the aspect ratio. Therefore, armor-piercing bombs require high-density and high-strength tungsten alloys. Qin Zhenhua cannot study this tungsten alloy.
, it can only be left to domestic professionals for research.
In China, Huang Lao is the first to be the first in the field of powder metallurgy because he is the founder of the domestic powder metallurgy field. He helped him to start this project.
With the development of time, many universities have also started the course of powder metallurgy, and have corresponding research rooms. There is also a national key laboratory for powder metallurgy. Since I am back this time, of course I will not let it go.
Qin Zhenhua's slightly inferior minded mentality disappeared after hearing these introductions and immediately became excited.
"If we have a more suitable tungsten alloy, then our armor-piercing bombs will have stronger performance. Even if we use our current 100mm rifled gun, we can still hit its 300mm penetration depth!"
The same gun has different shells and different armor-piercing capabilities. Now, the 100mm rifled gun equipped with a large number of domestic 59 tanks has the original penetration depth of only more than 100 mm, in front of modern tanks,
It's just that I can't do anything, and I can't even beat myself.
Now, with the introduction of the 105mm rifled gun technology from the UK, there was the sliding belt technology that was most needed in the secondary caliber armor-piercing projectiles. Later, it was applied to its own 100mm rifled gun, and the old gun was immediately put into the old tree.
It's a comeback, and now it's able to penetrate more than 200 mm.
Of course this is not the end point. If there are more advanced armor-piercing materials and larger aspect ratios, the armor-piercing performance will definitely be further improved.
As for our 105mm rifled gun and the 120mm and 125mm smoothbore guns that are being compared, the penetration depth will be able to exceed 400mm, or even break toward 500mm.
At the same time, this powder metallurgy technology not only fires armor-piercing bombs, but also fires ceramics. So, ceramic armor technology can also find suitable materials from powder metallurgy technology.
Materials science determines the development of a country's basic industry, which is definitely not a big deal.
Qin Zhenhua, with excitement, walked into the National Key Laboratory of Powder Metallurgy with Mr. Zhu. In the laboratory, there was a device like a large drum washing machine. At this time, the device was working.
In the front of the device, several people were wearing white coats, waiting for something there.
Qin Zhenhua and Mr. Zhu could only observe through the glass. Looking at these people who were doing scientific research, Qin Zhenhua's heart was full of envy. He had thought more than once that he wanted to become a scientist of this type, but it was a pity that he had created.
After getting involved, I eventually became a worker in a tank factory.
Now, Qin Zhenhua looked at the people there to study. They were operating the equipment, and a buzzing sound was made inside. It was a vibration from the inside caused by the high frequency stimulation. It can even be said that it is every
A particle that makes up the substance is shaking.
I don’t know how long it took, but the machine inside finally stopped ringing. Then, the device was turned on, and the workpiece inside, which was still in a high temperature, was taken out, and it was a round rod about one meter long.
The whole body is black and shiny, and it looks like a tungsten alloy.
After all this was done, they turned back. One of them waved to Mr. Zhu with a smile, and then walked out quickly.
"Old Zhu, what wind has blown you?" After taking off his white coat, the person who came out also showed his white hair and said to Mr. Zhu.
"Come here for a meeting, and you have time, come and have a look." Zhu Lao said: "Lao Huang, how have you studied?"
"The 78th test is underway, and the test items have come out. Wait for testing to see how the effect is." Huang Lao said: "Who is this kid?"
Qin Zhenhua is over 20 years old. In front of this old senior, he was called a child, which made him speechless.
"Old Huang, my name is Qin Zhenhua. Is the equipment in yours a low-pressure hot isostatic vacuum sintering furnace?" Qin Zhenhua asked.
As soon as this sentence came out, Mr. Huang opened his eyes wide and looked at him steadily, with incredible expressions in his eyes: "How did you know? Are you also an expert in powder metallurgy?"
This device is the latest masterpiece developed by Mr. Huang. Even if it is placed in the world, it is still at the leading level in the 1980s. I just don’t know how Qin Zhenhua could see it all at once?
Powder metallurgy requires a special sintering furnace, but powder metallurgy still needs to be divided into many steps during the smelting process. Among them, different steps are still required in different ways. When using high-frequency induction to melt, it is necessary to
It is in a vacuum state, which can avoid certain oxidation reactions with the air. After melting, if you want to sinter, you still need to pressurize, and the pressurization is divided into low pressure and high pressure. Different steps are quite cumbersome.
In order to improve production efficiency and reduce the loss of the intermediate steps, Huang Lao creatively concentrated the dewaxing, sintering, thermal isostatic pressure, etc. into a set of equipment. This set of equipment is the National Key Laboratory of Powder Metallurgy
The most advanced device.
Unexpectedly, the young man in front of him could see it all at once.
