Chapter 90 New Armor Recipe (Subscribe)

Wang Lai, as the head of the Armament Division, this kind of information comes from his mouth, and he can say it very clearly without any special preparation:
"The armor used by our navy can be roughly divided into five generations.

"The first generation of armor was wrought iron armor, and the warships at that time were also collectively referred to as iron armored ships.

"The second-generation armor is a composite armor formed by splicing steel for the exterior and wrought iron for the interior.

"The third-generation armor is to add nickel to the steel to form a tough alloy steel armor.

"The fourth-generation armor is based on the third-generation armor, using the surface carburizing hardening technology.

"During the manufacturing process, the armor surface is uniformly infiltrated with carbon, which increases the carbon content of the armor steel surface and makes the armor surface harder.

"At the same time, the carbon content of the inner layer of the armor remains unchanged, so it can maintain the original toughness, strengthen the defense ability and maintain the installation performance.

"The fifth-generation armor, on the basis of the fourth-generation armor, adds additional chromium elements to form nickel-chromium alloy steel, which improves the armor performance again.

"At the same time, the treatment method of carburizing has also been changed from carbon burial to carbon blowing, and the overall performance is more superior.

"The case-hardening armor that everyone usually refers to now usually refers to the fifth-generation armor, and the full name is 'Ni-Cr alloy steel armor using case-hardening treatment'.

"The fifth-generation armor with a thickness of 160 mm is now equivalent to a wrought iron armor with a thickness of 430 mm.

"The most important thing is that the hard case layer of the armor can smash the tip of a traditional shell, allowing the shell to explode directly on the outside, or simply fail.

"At the beginning of the war, our fifth-generation armor was just applied, and the armored cruisers built in the Daqin Sea all used 160 mm thick fifth-generation armor.

"After the war, it was discovered that the shells of the 300mm main guns of the Xiyi battleships could not penetrate our armored cruisers.

"On the contrary, a large number of Xiyi cruisers and a large number of medium-caliber naval guns can often smash the surface of our battleships and have to go back to the port to repair.

"So the battleships designed at that time were equipped with 240mm thick fifth-generation armor at most. If it was thicker, it wouldn't be needed, and the enemy wouldn't be able to penetrate it anyway.

"But later, we summed up our combat experience with Xiyi respectively, and each invented the 'cap-piercing armor-piercing bullet', which greatly reduced the armor advantage.

"The armor of the latest battleships has been piled up to a thickness of 300 mm, otherwise it would be dangerous to engage in close-range fire."

Zhu Jingyuan listened to Wang Lai's introduction, and compared with the relevant memories of his previous life, he had a rough judgment on Daming's armor craftsmanship.

Daming's current fifth-generation armored steel is almost the standard armor in the era of dreadnoughts.

The full name is that long list, commonly known as Krupp Steel.

Because the German Krupp company first added chromium to the nickel alloy steel and applied the carbon blowing method, it is the owner of this phased patent.

After other countries bought patents, they made different optimizations according to their respective situations.

These armor steels were used until the end of the First World War.

The development of armor technology after World War I, mainly on the basis of Krupp steel, continued to add molybdenum and copper elements.

Continue to improve strength, toughness and corrosion resistance.

According to the current generational division standards of Daming, these can be regarded as the sixth generation armor.

This armor was used until the end of World War II.

Those last-generation battleships on Earth basically use this type of armor.

The development of armor technology after World War II has gradually penetrated into the control of trace elements and more advanced production processes.

The final product is the support structure and pressure hull of nuclear submarines, as well as the flight deck of modern aircraft carriers.

Zhu Jingyuan, a keyboard politician and amateur military fan, does not understand the specific production process of armored steel, but only knows the general direction and remembers several main components.

With the current technological level of Daming, those new armor formulas that appeared after the First World War should be ready for research and development.

There is no upper limit to the pursuit of naval armor performance, and it is not the limit that the enemy's capital ship cannot penetrate its own cruiser armor.

The armor defense capability of the unit thickness is better, which can further reduce the armor thickness and weight while ensuring the original defense capability.

It can make the secondary warships have better defense, and also allow the main ships to gain greater speed.

So Zhu Jingyuan nodded lightly, affirmed Wang Lai's introduction, and directly put forward his own request:
"Now it's time to start trying new alloy formulas, which is an exploration of the sixth generation of armor.

"There should be manganese in the current armor alloy material, right?
"If you don't have it, add it in, the ratio is about three-thousandths.

"Then try adding molybdenum at a ratio of about [-]/[-].

"At the end there is copper, which is about two-thousandths of a percent.

"If the steel uses a silicon-containing deoxidizer, the silicon content should be controlled to about three thousandths.

"Anyway, let's see if there is a good effect."

Wang Lai and the left-behind craftsmen of the Armored R&D Bureau carefully recorded Zhu Jingyuan's requirements and recipes, and prepared to have them tested immediately.

They were clearly looking forward to it.

Materials science is often chaotic.

It is difficult to predict what effect the new ingredients will have after adding the original materials.

Most of the materials with excellent performance are not only piled up by the number of experiments, but also many are accidentally produced in the experiments.

The exploration of new armor materials is theoretically the most important task of the armor bureau.

Routine exploration is also being done all the time, and people in the material department are testing various solutions all day long.

However, there has been little substantial progress for more than ten years, and the process can only be continuously optimized on the original formula.

Zhu Jingyuan now specifically proposed several new material formulas, that is, adding a few more items to the daily test list will not affect the daily work of the Armored R&D Bureau.

If the formula provided by Zhu Jingyuan showed obvious excellent performance, it would be an absolute surprise.

Then the follow-up research and development work will immediately move closer to the refinement of these formulas, and the priority of other things will be reduced.

Since Zhu Jingyuan participated in the affairs of the Ministry of Industry, the ideas he put forward often have very good results. The most typical representative is aircraft design.

If Zhu Jingyuan can still come up with very effective ideas in materials science full of chaos, it will be more surprising than other normal research.

Although I don't know if these materials are effective, Wang Lai, the head of the ship division, and the craftsmen of the Armor R&D Bureau are still full of expectations.

Zhu Jingyuan's mentality is relatively flat, and he does not expect to have very good results immediately.

Because the formula is likely to require technical cooperation, I am not sure about the technical level of Daming and whether it can achieve the effect of those formulas, so I did not say too much.
