The Troublesome Hero Among the Heroes

As the continent’s best arsenal, many kingdoms will commission Holy Land to develop and produce some equipment.

This time, located in the southern part of the kingdom of Biberach, the kingdom of Reybach, which occupies the north bank of the river, commissioned the forging of Holy Land to develop and produce a new type of Raptor armor.

In the workshop, Charles saw a 1:1 Velociraptor model.

The Velociraptor looks a lot like the Three-Horned Dragon of the late Cretaceous without horns. It is more than three meters long, with a back height of nearly two meters, and a head that occupies nearly one third in length. There is a tall bone shield behind the head, and a stubby tail behind it. The total length can be close to five meters. It has short and wide feet and is good at running with heavy loads.

"Although it usually likes to graze slowly on the grass like sheep, it does not seem to be worthy of the name of Velociraptor." Halkara was introducing this lesser dragon to Charles, "But it It is the lesser dragon that is used the most by dragoons on the ground. And its name comes from their performance on the battlefield."

Charles was nodded after listening. Dragoons ride on such a armored armor. The next few tons of guys quickly rushed into the battlefield, and for the infantry, it was simply a situation of crushing all the way.

On the battlefield, these dragoons have also become the focus of various long-range strike forces. As long as they show up, let's cover one round with firepower.

Now there is a problem with the armor of the Raptor equipped with the Raptor commissioned by the Kingdom of Reybach.

Party A will naturally put forward a variety of needs to Party B, ranging from colorful black to changing the main color of the APP according to the user’s phone case. Party A’s Boss has a wide range of ideas that is universally recognized.

This time, the core requirement of the Rebach Kingdom for the armor is "lighter, harder, and cheaper."

Sometimes the simpler the problem, the more difficult it is.

This time is going to die for the dwarves.

This world has been in battle, and various war-related technologies have developed rapidly, but it has also reached a bottleneck stage.

The armor is lighter and harder than the previous ones. It's not difficult. Just pile it up with magic materials. But in this way, the cost will go up.

Previous transmigrators brought chemistry knowledge. People in this world also have the concept of elements, and they also know some alloy knowledge.

However, not all metals are as easy to extract as gold, silver, copper, and iron.

For example, manganese and tungsten can increase the strength of steel. The mass production of the former requires electrolysis technology, while the latter requires a series of physical and chemical reactions to obtain tungsten powder.

In this world of insufficient productivity, the large-scale production of these two metals is extremely difficult, and they can only be produced on a small scale using methods similar to laboratory preparations. This makes their prices not much lower than those of magic metals.

The dwarves who can only work on ordinary steel materials were helpless, and even invited foreign aid to help.

It's just that Erbach, who had been invited in the past few days, and Wolf, who had traveled through before, could not come up with any good solutions.

Now there is a long table in the workshop not far from the gate. On the table are several steel plates marked with numbers. A blackboard was erected on the side of the table, and Bu Laien and Erbach discussed in technical terms from time to time while writing and drawing on the blackboard.

During the period, the students brought by Bu Laiente and Erbach also occasionally asked one or two questions, but most of them listened.

Charles was listening to a heated discussion in front of a few samples made by Bu Laien and Erbach in the workshop.

After listening for more than an hour, Charles also heard some ways.

The power of Velociraptors is very strong, and the armor prepared for them is generally 5 mm thick. In extreme cases, they can put on a layer of armor before the battle, but then they will only have the power of a battle.

The armor used by the Raptors in the Kingdom of Rebach is made of tempered high-carbon steel. If you want to increase the hardness, it will inevitably make the armor lose its toughness and become brittle.

The current research direction of the two professionals is whether alloy steel can be used to improve the performance of armor without greatly increasing the cost.

According to Erbach, their Academy seems to have discovered a way to smelt ferromanganese with pyrolusite and iron ore, and suggested that Bu Laien use ferromanganese to produce manganese steel.

Of course, Charles, who didn't know that the metal called "Manganese" mentioned by the two big men was manganese, was confused in this paragraph. Many of the metal terms here are different from those in the previous life. Even if he knows how to get Harvey armor, he doesn't know how to say nickel, and what the physical and chemical properties are.

And he doesn't want to reveal his identity as a transmigrator. He wants to make a fortune in the back.

His grandfather is a linguist, and his family does not have the slightest background in metallurgy and materials science. He can’t pretend to be taught by the metallurgical expert grandfather like this Feng Chen in Qicheng Universe, or Lin Mouhua used the excuse to meet an old professor near the station when he was in the army.

Fake Elizabeth? Just kidding, how could this kind of essay-reading thing be hidden from her. Her identity was exposed. She was 70% likely to kill herself, Halkara was 20%, and the remaining 10% was divided equally between coriander and red leaves. The reason is not elaborated in the book.

So Charles can't choose those very professional knowledge to play the necessary pretender routines of transmigrator.

Currently, Charles wants to do things out of a playful mindset, and secondly, he wants to go online with the forging Holy Land with a peculiar style. This requires him to come up with something that may not be necessary. On, but something that can make professionals shine.

And Charles does not have much reserves of armor, metallurgy, and materials in his knowledge reserve, so he has limited choices and can only find references from other places.

The body armor is first ruled out. First, he doesn't know what materials can achieve the Kevlar effect. Second, the weapons that the two worlds need to face are different. The most important thing is that this method is not metal enough.

All kinds of alloy steel are also excluded. The knowledge of materials science is traceable. You can accidentally put the wrong ore to make stainless steel, but you are impossible to think of stainless steel out of thin air.

Harvey armor was also ruled out. This thing was used to armor battleship. The thinnest Harvey armor made by the United States in the late World War II was also a few centimeters thick.

The reasons for the elimination of composite armor are similar, and it cannot be made thin and light enough at the current level.

The last is a kind of armor that was famous in Charles' world...

"The idea of ​​this thing seems to be used for reference." Charles thought, "And the craftsmanship is enough. Mature. It seems that there is a misunderstanding in the thinking of the dwarves, and I did not expect this."

The discussion between the two big men and the workshop technician and the old master worker has temporarily come to an end. Now everyone has a tea break. time.

Bu Laien noticed Charles looking thoughtful, so he asked: "Charles, do you have any thoughts?"

The people around him laughed and did not speak. They have the same idea as Bu Laien Te, and regard this as a pleasure.

"The idea is a little bit." Charles said, imitating his grandfather's actions and tone.

This time Bu Laiente and Erbach, two old friends of Charles grandfather, were happy.

Elbach pointed to the blackboard on the side and said to Charles: "Then you go and write your thoughts."

"All right," Charles said cutely. "If I’m wrong, don’t laugh at me."

Naturally no one will laugh at an eight-year-old child on academic issues. Which of them has not spent more time in school than Charles’s age . And the sum of their school time is not as good as Harkala, who is drinking tea elegantly in front of the background board.

Charles walked to the blackboard, he first drew a ▱, and then added a few strokes to form a three-dimensional drawing of a steel plate. Then he drew a net parallel to the steel plate under the steel plate. Then, two steel plates and a net were drawn repeatedly under the net, forming a structure of steel plate-mesh-steel plate-mesh-steel plate. At the bottom, he drew a "⌸" profile view.

In the end, he drew a lesson of small flowers on the side, and then focused on the soil under it and the root system in the soil.

After Charles finished drawing, he turned his head and found that the expressions on the faces of the people at the long table were different from what they had when they were relaxing after drinking tea.

"Tell me what you think." Bu Laien said to Charles, "Don't worry, no one here will plagiarize your thoughts."

Charles cleared his throat and pointed. The root system under the little flower he painted said: “Everyone knows that when we pull out weeds and other plants, their roots will come out with the surrounding soil. This is because these roots firmly grasp the soil. The reason."

"I heard the two masters just now, if you make steel harder at the same time, they will become brittle due to the decrease in toughness, which will cause cracks when subjected to impact. "

"At this time, I thought that if high-tenacity metal nets similar to plant roots are added to the steel plate, these nets can be closely combined with the steel plate to help the steel plate bear the force of cracking. Can this make the steel plate have both hardness and toughness at the same time."

Charles just thought of the legendary depleted uranium armor, which is a mesh made of depleted uranium alloy and embedded in steel to make an armor block.

Then he thought of reinforced concrete from this. Although concrete is hard but brittle, it is compressive but not tensile. If there is pressure acting on a beam made of pure concrete, the compression area above the concrete beam is fine, but the tension area at the bottom will crack. Therefore, steel bars with higher toughness than concrete are added to the concrete, so that the steel bars can bear the tensile force under the concrete beams. Expanding from beams to slabs is the reinforced concrete floor in common buildings. (Interested readers can find "Materials Mechanics" and "Structural Mechanics" to study)

In Charles's eyes, the vertical armor is cut for people and the horizontal reinforced concrete floor is stepped on the mechanics. It should not be much different, so he proposed an armored deck structure similar to a reinforced concrete floor slab.

At the same time, Charles feels very strange that concrete is used here, so the person who taught them to use concrete should also teach them to use steel. So why didn't the dwarves think of this method? Charles doesn't think he has the aura of lowering wisdom, and there is probably something hidden in it.

"The hammer is on!" Bu Laien suddenly jumped up from his chair, and then shouted at the boss of the workshop, "Hurry up and ask the Pope to come over!"
