My German Empire

In the history of the United States, there is a military person, his temperament, bad temper, and is called the most tenacious bastard in the navy. He often fiercely insults and ruthless intimidations for colleagues and subordinates. Some people say that he "will not be better than everyone's days", even our own wife children, and this guy smoking and drinking, but also colorful Woman, private life is extremely shaking, living like a hooligan.

But such a personalized guy, it became the greatest military fullness in the history of the US Navy! Whether it is a submarine, cruiser, destroyer, battleship, aircraft carrier, or Navy Airlines, Navy logistics and laboratory research, he can play, even with the president to engage in diplomacy, he is quite proficient.

This guy is one of the four naval five stars in the history of American history: Onester Joseph.

In the military career, Onester had countless people, and it has also ruined a bunch of people, the stinky temper, people are annoying. The President of Rosford, but he is only known. Oneste's talents are full of perseverance, perseverance! In 1938, he enhanced him in the neighborhood of the Navy, and he was shortly to appoin the commander of the North Atlantic fleet.

"Today, there are four warnings to lose contact."

This tonnage of this warning ship is small, even if the last torpedo will still sink, basically no time to save the message. Plus the sea defense circle is extended to 1,500 kilometers, and it is difficult to reinforce in time. From Declaring War to the present, they have lost more than 20 vessels, and they are sinking by the other submarine.

"..." Because Kodor Her's immerses rushing down, I can't wait to immediately calm down Roosevelt to the Soviet Union. The United States has already provoked this big trouble in Germany and can't get another Soviet Union. "What do you think?" He secretly decided to let the Soviet price of the Soviet contest!

Inester took out a document. "This is the combat plan I have developed, we should take the initiative to attack the Germans."

Berlin, Germany, Janik came to Krupp, inspected the research progress of new armor.

Different classifications of tanks in nature, materials, manufacturing methods, composition, etc. High quality rolled homogeneous steel armor (RHA) has become the mainstream product of Second World War II Tank Armored in its dense structure, good resistance and processing process. RHA has become a standard of armor anti-elasticity.

The alloy steel steel armor is to add alloying elements such as nickel, chromium, molybdenum, and manganese, so that the hardness and toughness of steel armor are increased. Take the famous Nickel-chromium alloy steel armor in World War II, 2% ~ 6% nickel, 1% ~ 2.2.5% chromium, 0.2% ~ 0.6% molybdenum, etc. in ordinary medium and low carbon steels, and pass through special heat treatment Process, you can make hard and tough, hard-tough high-grade alloy steel armor. Its yield strength reaches 720 to 900 cattle / square millimeters, more than double the ordinary steel armor.

These Germany can come to Germany for the lack of resource, these are the veritable "rare metals", and the quantity cannot meet the industrial production.

So the German traditional technology advantages have played a huge role, and the armored armored armored nickel alloy steel armor in the tiger tanks is very different. It is precisely that the tiger is not an alloy armor, but uses trace manganese molybdenum. Steel A, generally called steel armor.

Can molybdenum can improve the ductility of steel and make it tough. The molybdenum mine in Germany is very small, only in Norwegian minerals. Since the Norwegian molybdenum mines were fried since the Second World War, the armor quality of the German tank declined seriously.

In addition, Germany can only use armor surface quenching carburization techniques to make up for the shortcomings of armored steel elements.

Carbon-based processes are now commonly mentioned by surface hardening processes.

However, its performance and weight gain are incomparable.

For example, if the same 20 mm steel sheet is that the protective performance can be increased to 26 mm, but the weight is 53 mm thick steel sheet. This is also an important reason why Germany is high in late World War II and the weight of tanks. 56 tons of tiger tank If you use nickel-chromium alloy steel armor, you can minimize 10 tons; its mobile will have significant improvement.

It is also a defect in the use of surface carburizing armor to reach armor hardness. It is a great decrease in the armor. Especially in the late 44th, many armored process declined Germany's tanks are not being broken by allies. It is a large area of ​​armor. There is a record showing that the first armor of a tiger king was cracked after the SU-152 hit, but did not break through, which is this reason.

In addition, the surface hardening treatment process is also quite cumbersome. This is not a simple quenching. The so-called carburizing is low-temperature back on the surface of the steel sheet, a heating and quenching, high temperature carburizing tempering, secondary quench cooling treatment and other processes It can be described as fees. Moreover, the steel sheets are also required, and the steel sheet used is a low carbon steel sheet (the carbon content is less than 0.25%), and there is enough carbon that can no longer be carburized.

Fortunately, in this time, Jianki discovered the resources of European countries, although rare resources were still rare, but they also met the military demand for the Germans. Germany's armor has finally embedded alloy steel roads for rare metals such as nickel, chromium, and molybdenum.

However, Jenik is not satisfied, continuing to improve steel smelting technology, so that impurities such as sulfur, phosphorus in steel armor are reduced to 0.01% by vacuum smelting, electric slag remelting, etc., and the anti-elasticity of steel armor is more floor.

Under his guidelines, the research department has developed aluminum alloy armor and ceramic composite armor.

By comparing the aluminum alloy and steel armor, the effect of aluminum alloy is slightly different, but the effect of preventing breaking the nail is better than steel armor, plus the stiffness of aluminum alloy is high, and can save Thin, beams and other structural parts, thereby alleviating the weight of the whole vehicle. Therefore, aluminum alloy armor is widely used as master armor of light armor vehicles.

As for ceramic composite armor, its structural cream sandwich biscuits is almost. The panel layer is a high hardness alloy steel. The bottom layer is a strong alloy steel having a toughness. The middle layer is composed of many ceramic balls, and the glass fiber reinforced resin is filled in the gap between the round balls.

In this way, when a shrouded portrait passes through the "sandwich biscuit" level, the warhead has gone, and a lot of energy is consumed. Then, the more tough ceramic ball of the intermediate layer decomposes the main impact of the bullet, and finally, there is no more embarrassing ability when I lose most energy.
