"So far, we have known that the aspect ratio is a very important indicator for armor-piercing bullets, but it is not easy to make such a long and thin pole." Qin Zhenhua began to talk freely.
Everyone knows this most basic technical key, but if you know it, it does not mean that you can make it. The most typical example is the Soviet Union.
Speaking of the Soviet armor-piercing bombs, even in later generations, it was criticized. For example, the exported steel core bullets were fine. Even if they used them themselves, they were all two parts of the bullets, and the core was divided into two sections.
Then use a steel sleeve in the middle to cover it.
It looks quite bulky and has a high aspect ratio. Don't the Soviets know that the thinner the longer the better?
Of course they knew that, but they were unable to make breakthroughs in alloy smelting technology and did not have the right materials at hand, so they could not make it.
This requires the support of metallurgical technology.
In terms of the material of the armor-piercing bullet core, for a long time, engineers have locked in tungsten alloys. Tungsten alloys are quite hard substances that can be found in the world and have a large specific gravity. However, it has one disadvantage.
It is quite brittle! It is easy to break, so even if it is an armor-piercing shell using tungsten alloy, it also has a steel sleeve outside the core. The shells of the main tank guns of the early Western forces, such as the M735 and DM13, were like this.
Now, Qin Zhenhua boasted that he did not blush at all: "We used the world's most advanced liquid sintering technology to create. The process of this technology is quite complicated. First, we need to use tungsten powder, iron powder and nickel powder.
When the metal powder is mixed in proportion, pressed into the required long rod shape and heated to high temperature, we all know that tungsten has the highest melting point, so metals such as iron and nickel melt first; these liquid molten metals will fill the gaps of tungsten particles.
Just like when we pour water into a cup full of beans, the water will fill all the gaps. At this time, tungsten reaches a semi-melting state and forms a solid matrix structure with liquid iron, nickel, etc., which we think
The most qualified hard alloy is needed. Then, in order to increase strength, after cooling, we will also apply traditional technology to repeatedly forge and roll the formed tungsten alloy rods, and finally make a tungsten alloy core."
The tungsten carbide used in the past is more advanced than tungsten carbide, which is the tungsten-based armor-piercing bomb created by this liquid phase sintering technology.
Of course, this technology is not actually confidential. What is confidential is the specific process. The temperature of a certain manufacturing is the key. In the 1960s, when the United States and Germany jointly built the MBT-70 tank,
I did this kind of armor-piercing bomb, but the process was not advanced at the beginning.
Now, if we want to develop this process into a mature process, it is Israel. Israel has developed this process and created the M111 armor-piercing bomb that they are most proud of. This armor-piercing bomb is the first in the Western world.
A tungsten alloy armor-piercing bomb that is not protected by steel sleeves.
The Israelis themselves are quite confident in the power of this armor-piercing bomb. Now, Qin Zhenhua has revealed the process of processing advanced tungsten alloy armor-piercing bombs in the Eastern powers, and they use this technology, which is even more amazing. The road to success is even more amazing.
There is only one, this one has flowed out, and the great powers of the East have also flowed out. How did they do it?
Of course, the Eastern powers have the advantages of the Eastern powers. They have the largest tungsten ore in the world. They have never lacked tungsten. Although this thing is relatively expensive, they are easy to obtain and can easily study its smelting technology. So, now they get it.
This advanced armor-piercing bomb is naturally as expected.
"Your side also used liquid phase sintering technology?" said an engineer opposite: "What is the aspect ratio of your armor-piercing bomb?"
For armor-piercing bombs, the aspect ratio is a very important indicator. The larger this indicator, the stronger the armor-piercing bomb's armor-piercing ability.
"Well, we can now achieve the data of 18," said Qin Zhenhua.
When he said this, he was a little embarrassed. Obviously, he was considering whether to say the actual situation. The real data may be larger than this.
This is also a practice of various countries. Many technologies on their tanks are kept confidential, including how thick your armor is and how strong your armor-piercing ability is. They must be kept strictly confidential. Only in this way can they work in one fell swoop when they are on the battlefield.
However, the number 18 that can be announced to the public is already relatively strong. After all, most armor-piercing bombs have just broken through 10 at this time, and the advanced one is that they can just reach 15.
The other party’s progress in this regard is indeed effective.
"So, if we can, can we exchange technologies with each other?" Mr. Tar asked.
Everyone's technical level is similar. When exchanges with each other, they can learn from each other's strengths and weaknesses. Of course, this is only limited to when both sides are at the same level. If not, then the West is above the top and will definitely not use relevant technologies.
Teach the great powers of the East step by step.
Qin Zhenhua showed a meaningful smile on his face: "Of course we welcome this, but this is our core technology after all, and it has to go through a lot of processes. So, for the time being, I suggest that we should exchange the finished product.
Some, how?”
He was right. Even the top secrets of armored soldiers were not allowed to make decisions even if the Huang Lao led the team. He had to ask his superiors and had to go through many processes. In the end, it might be delayed for a long time. Now,
It's better to do what you can do first.
Now, exchange some finished products first, and take them back and study them together. This time I came here, I originally planned to communicate.
Mr. Tal nodded.
"We want to invite you to stay for a while and inspect us. By the way, we also want to hold a seminar, everyone will sit down and study the development of tank technology and future prospects together. I don't know your intention.
how?"
Tank technology seminars and such meetings have also been discussed at home, and internationally, of course, there are experts from both sides now sitting together to study future tank technology, enhance friendship with each other.
In the past, only European developed countries had this qualification. Oriental powers did not have this qualification. After all, they only had five pairs of heavy loads and had no advanced technology. But now, the inspection team of the Oriental powers that visited this time is also
The plan to improve tanks as infantry fighting vehicles was very good, so Mr. Tar had a sudden idea and wanted to hold such a meeting.
Qin Zhenhua looked at Huang Lao, and Huang Lao nodded seriously.
What's wrong with this? Isn't it just bragging? If you want to fool me, Qin Zhenhua is quite good at it.
