In the laboratory of the Academy of Military Sciences.

A group of people were looking at an irregular piece of metal.

Zhang Pingyuan took a deep breath. This small piece of metal took him several hours.

What made him somewhat fortunate was that the information Dean Shen gave him contained extremely detailed processes and casting methods.

Even so, with his ability, he almost failed the first time he made it!

If it were someone else, or if they wanted to mass-produce, it would be almost impossible.

I originally thought it was just a small piece of alloy, but with my accomplishments in this field, I could complete it on my own.

Now he had to call together a team from the alloy research and development department within the Academy of Military Science to work together.

Zhang Pingyuan took a breath and said in a deep voice.

"Before formal research and development, we still need to conduct simple tests on this alloy."

Regarding the specific manufacturing process of the alloy and related documents, he directly submitted it to the team.

Countless people below saw the contents of the document, and the expressions on their faces at this moment were exactly the same as Zhang Pingyuan's before.

This special and complex alloy is simply beyond their knowledge.

But at this moment, no one dares to question the authenticity of this document.

First of all, Zhang Pingyuan is the director of the Academy of Military Sciences, and his prestige in the field of alloys is relatively well-known.

Secondly, the alloy in the document is now lying quietly in front.

This is not doubtful.

Among the crowd below, a young researcher stood up and asked.

"Director Zhang, according to testing, the Rockwell hardness of this alloy has reached level 10 or above?"

Zhang Pingyuan nodded quietly.

Grade 10 is the standard for measuring Rockwell hardness and is not used in more accurate scientific research data.

For alloys, the hardness grade is usually measured based on the Brinell hardness grade.

He said seriously.

"Well, measured on the Brinell hardness scale."

"The hardness of this alloy exceeds the Brinell hardness scale!"

"Based on the current level of scientific research, further testing is needed for a more precise measurement."

The sound fell, causing many researchers in the laboratory to express surprise.

"Exceeding the Brinell hardness scale?"

"This only shows that the hardness of this alloy is indeed extraordinary."

"Alloy can actually achieve this kind of hardness?"

"..."

The noisy sound lasted for a while, and then became much quieter.

Zhang Pingyuan nodded.

In laboratories, most are Brinell hardness testers.

This hardness test mainly uses steel balls to leave roots on the material to be tested.

Then test the hardness of the material based on the diameter of the root.

But there is no way to leave any indentation on this piece of alloy.

The steel balls on the hardness tester almost burst under pressure, and there was nothing they could do.

If you want to test the detailed hardness of this piece of metal, you can only use Vickers hardness, which is widely used in industry.

Among the crowd, a researcher suggested.

"Can I simply test the hardness of this alloy?"

The entire research team in the laboratory is unanimous.

An alloy of this strength is simply unique.

They are also curious about how hard this alloy is!

"Okay." Zhang Pingyuan nodded and did not reject the proposal.

Although the cost of this new alloy is high, it is not yet sky-high.

Moreover, this alloy itself is used for experiments, so even if it is damaged, there will be no problem.

As soon as the words fell, a researcher couldn't help but start taking action.

He took out a key from his pocket, selected a relatively sharp key, and slid it back and forth on the smooth metal.

A "buzzing" friction sound came out.

Countless people around him also showed extremely curious expressions.

Although the existing data has reflected a certain degree of hardness, in people's hearts, some things must be "seeing is believing."

After the researcher rubbed back and forth, some extremely fine metal particles appeared on the surface of the alloy.

Obviously, these metal pieces did not fall off the alloy, but were the keys in his hand.

He blew gently, and these metal fragments disappeared.

The extremely smooth surface of the metal was revealed to everyone again.

After observing through magnification, it turned out to be nothing beyond anyone’s expectations.

"Sure enough, there aren't any scratches!"

"The hardness of this metal is at least diamond level!"

"..."

Everyone also nodded with satisfaction.

The scientific researcher exhaled and took the key back.

Key? That's just a small fuss.

How can it be possible to use this kind of thing to really test the hardness?

I saw him take out a box of diamond-shaped diamond needles from an ordinary tool box!

Of course, it has another name, Mohs hardness pen!

This is an extremely simple and rough method for hardness testing.

Just use the diamond needle to make scratches on the metal surface to be tested.

Based on the scratches on the surface, the hardness level of the metal can be calculated.

Previously, the hardness difference between the two materials was too big, so it was normal for no scratches to occur.

Immediately afterwards, the researcher directly slid the diamond needle on the surface of the metal.

Under everyone's gaze, the drill needle kept sliding back and forth on the alloy.

This kind of diamond needle can cut glass extremely easily.

Ordinary metal can leave a deep mark without any problem.

Countless people are curious about the results of this test.

Hardness level 10 or above? How much is it?

In fact, there is never a strict limit.

Because of the hardness of nature, most of them have corresponding ores or metal substitutes.

There are no protective measures or paint protection on the surface of this alloy.

Among the currently existing metals and alloys, no matter how high the hardness is.

As long as the hardness levels of the two are close, there will be some scratches.

For example, a diamond drill tip with Mohs hardness level eight can also leave traces on diamond with the same hardness level ten.

Even knives are made of steel.

Some sharp instruments will produce some scratches after being rubbed.

Soon, the test is over.

After being amplified by the instrument, the extremely smooth alloy surface on the electronic screen shocked everyone.

Even if there are no scratches on the surface of the alloy, there are actually debris left on the alloy from the Mohs hardness pen.
