It is said to be cast iron, but in fact it is all steel. Pen, fun, pavilion www. biquge。 info comes from German armored vehicles, steel helmets, and even the steel bars stripped from the ruins of Homnitsch, all of which are steel with a low carbon content.

The blast furnace in the blacksmith village has the ability to melt it, but after the pouring is completed, it will inevitably be mixed with carbon, and its performance will be reduced.

Since it is a weapon used as a consumable, the industrial properties of metal materials are not much considered, at most they are used to make nails. Among the many products, cast iron is the most productive, on the one hand, its production process has been invented for 3,000 years, and on the other hand, only the most grenade shell, and bullet warhead are completely used. In the case of artillery shells, it is necessary to use a blower to blow air.

A group of soldiers collected metal near the breakthrough at the range, where the soil was so delicate that the fighters quickly sifted through a large number of metal particles - these were bullets.

A large number of pieces of broken iron were placed in front of Yang Mingzhi and others, and on the surface, it was no longer possible to see the shape of the bullet.

When a standard lead-core steel bullet hits a soft target, its shape barely changes, and it should still have a streamlined shape in the palm of your hand. Yang Mingzhi squatted down and grabbed a handful of iron particles, there were too many irregular fragments here, only a few of them were not violently deformed.

There are also some of them that are not deformed at all, and their characteristics are completely different from the others, and the traces formed by scraping the rifling are clear at a glance.

Yang Mingzhi held two bullets in his hand, and he said to Riguskov, who was waiting for the big-eyed Riguskov: "Here, one is the warhead of a standard German-made bullet, which was fired by Besica. This one is a cast iron warhead produced by the arsenal, and it is lucky that it has not shattered, but the overall shape has also changed. ”

Rigushkov nodded, the land of the shooting range will be swept aside after training, and the metal bullets fired will not be wasted, and they can still be used after returning to the furnace. These pieces of broken iron all came from the shooting of the junior battalion, and most of the warheads with cylindrical round heads turned into large and small pieces of broken iron.

"Just by hitting the wooden block, it will crumble, is it too much carbon mixed in during processing?"

"That's right, it's just too much carbon." Yang Mingzhi pinched his waist and said, "From an industrial point of view, these metals are just like waste. Rigushkov didn't want that, pure iron was soft, and when too much carbon was mixed in, the hardness increased, but it also became brittle. A large number of splinters can appear when you hit a wooden plank, and the armored vehicle that hits the enemy does not turn into a small piece of iron with nowhere to go? If such a warhead, how to guarantee flight stability? Accuracy is not guaranteed, and it is really only possible to shoot at close range, and the closer you are, the more dangerous it is for the soldier.

"They can't be processed into industrial products, but they have a new use as bullets." Yang Mingzhi said excitedly: "Ryguskov, think about it, after a bullet hits the enemy's body, it will explode into many small pieces like a cannonball, which can kill and injure the enemy to the greatest extent, and one bullet is enough to destroy the enemy's internal organs." ”

"Is there really such a bullet?" Rygushkov asked in surprise.

"Definitely exists! After all, this is what the deputy division commander said! Popov has been completely aroused by Yang Mingzhi's curiosity, this man from the East will definitely bring the power of the East, if the weapons design bureau makes such a bullet, even a soldier with poor shooting skills can be transformed into a terrifying combat force.

Looking at everyone's curious looks, Yang Mingzhi pointed to the piece of iron on the ground. "We all want the bullets to be as they were when they come out, and as a result, the poor cast iron has shattered, broken the moment it touches the plank, or it can become multiple fragments. Such a bullet has extremely poor penetration, but the erosive power is very strong, and one warhead splits into many, and its effect is probably the same as that of being shot by MG34 in short spots. ”

"Isn't this the effect of dummy bullets?!" Rygushkov said in amazement.

"But this is not a dummy bullet, we are poor now and we can't use lead at all, and all reloading bullets are iron. Because the only way we can get lead is to sift through the land with a screen on the battlefield, so that those warheads can be used by us. ”

Everyone was happy to say that.

Yang Mingzhi waved his hand: "We have also recorded these situations, and in the afternoon, we added a German-made reloading bomb experiment, and there was another unexpected gain in terms of results, now let's go back to the meeting." ”

In the past, the material used for reloading was very good, and although the bullet flew poorly, at least it would not crack if it touched the target. It may be because of the large-scale production movement, the arsenal has reduced the control of process and quality, a large amount of carbon is mixed into the molten iron, and good steel has become scrap.

In fact, most metals can be used as warheads, Yang Mingzhi thought of China, which is 10,000 kilometers away, and Yan Laoxi's Jin Suijun engaged in tin bullets for a period of time, after all, this metal is particularly cheap. It is only because its melting point is too low, the strong chamber pressure and high temperature cause it to fly out in an almost liquid state.

Everyone walked on the way to the research institute, Yang Mingzhi had already decided to start the experimental analysis non-stop, and he thought of these suddenly, seeing that he should make a big fuss about the bullet.

When he came to the weapons research institute, Yang Mingzhi criticized Rigushkov and Popov about the failure of the rocket, because they were mixing propellant agents. The first shot contains less ammonium nitrate, but the second shot contains a lot of ammonium.

After the two finished speaking, Yang Mingzhi stood up and briefly said: "Ammonium nitrate is used as a propellant additive, and it should not replace potassium nitrate at present, because the energy and gas produced during its chemical reaction are too violent. We know that the thrust of a rocket comes from the gas generated, and that the shell of our rocket cannot bear such pressure due to excessive gas expansion. ”

This is the best explanation in terms of the results of the experiment. Ryguskov admits that he had no idea that the ammonium nitrate would bring about a burst of power.

Yang Mingzhi took out a pen and paper and wrote down the equation of the chemical reaction, as well as the correct ratio of the mixture.

"That's what I should have told yesterday, because there was a delay except for those things. A failure of an experiment is not a bad thing, and from a dialectical point of view, we know the cause of failure with failure, and I am afraid that we will not make this mistake again in the future. When the ammonium nitrate in Catfish Village is mass-produced, we will mix propellants in this ratio. ”

Riguskov patted his chest: "I will honestly follow the process, but what about the explosives of the warhead?" ”

"There is no problem with explosives, it is still chemical fertilizer with wood chips, as an alternative to black powder, and we can produce ammunition with high cost performance."

The problem of rockets is better solved than the problem of bullets. The faster muzzle velocity makes the RPG a dozen accurate, and the shooter who is dealing with long-distance targets no longer has to adjust the shooting angle with experience and faith, as long as the mechanical aiming crosshair is aimed at the enemy tank, Yang Mingzhi said jokingly: "Everything is according to my orders, our fighters can easily do смотреть-пряжка-подождите (aiming, etc.)"

"So it will be so simple to fight enemy tanks later?" "With more thrust, we can shoot a warhead with a larger charge, and even if the enemy increases the thickness of the armor, we can still penetrate it head-on." ”

"Of course! I'll remind you that Catfish Village will also provide a lot of high-energy fuel weapons. Yang Mingzhi wrote down the chemical formula of hydrazine hydrate and pointed and said: "The special warhead produced with this compound as a raw material is the most powerful weapon that we will be equipped with in the future. ”

"Don't worry, sir, I'll get the job done." Rygushkov's straight waist is reassuring.

Yang Mingzhi nodded with satisfaction and started the topic of empty bullets.
