81-04 Wartime Technology

I see, you use corundum instead of alumina.

Jen listened to it beside her, and she was impressed by the idea.

No, it wasn't much of a compliment because it was an idea when supplies were scarce during the war.

"That's not true."... it's a good thing we use what war produces for peaceful purposes. "

I see... I see.

"If you add some trace elements to the corundum, will the enhancement width increase?"

Huh?

It seems that Arnold was the first to hear that what Jen said was a principle common to [Magi] materials.

"Why don't you try the corundum with about a percent of mythril silver?"

When Jen asked Ka-chair that,

"There's enough material in the lab to do the experiment."

and the answer came back.

Alright, let's do it then.

Eila suddenly became enthusiastic.

Well, let's start with the experiment.

Groma told me about it and went straight to the lab.Jen and Arnold were there too.

Reiko and Cher followed, of course.

First of all, it's a corundum.

Crystals of clear aluminum oxide.

The specific gravity is about 4. The melting point is 2050 degrees Celsius.

Morse hardness is 9 after diamond.

Add 1 percent of mythril silver to it by weight.

"'Addition'"

Jen used engineering magic to add mithril silver.

Ooh!

"It's beautiful..."

Trace amounts of silver often had little effect on the color of the minerals, but the miscellaneous silver seemed slightly different, resulting in a pale lemon crystal.

I think it's going to work out in one shot.

Jen, who is able to make these magi materials, went out on her own.

In the meantime, I decided to investigate the physical properties of this [Magi Korandom].

The nature of the default is almost identical to the original corundum.

This was to be expected.

The question was, how much strengthening was possible with magic?

This [Magic Power Enhancement] was not done by Jen, but by Eila.

Because Jin is likely to add more powerful effects than usual.

"Hmm, this is quite..."

It's roughly five times stronger!

That's enough.

"But the destructive properties..."

The hardness is sufficient from the beginning.

The problem is' toughness', that is, 'tenacity'.

In addition, "destruction characteristics" will also be important.

To give you an example, if a force is applied, will it break suddenly when it exceeds the limit like glass, or will it cause a deformation (plastic deformation) that does not return?

In the case of iron, it is called the elastic limit, and if the force is stopped, it has a limit to restore to the original state.Beyond that, it deforms (plastically) like clay and remains bent even after the force is removed.

The preferred properties of glass and iron vary depending on the application, but as a material used for the skeleton of a golem, it is believed that it is preferable to "stick" without being suddenly destroyed like iron.

"I don't think I can do that unless it's metal."

I see.

"I think so too." That said, isn't strength enough? "

Since it is not intended for combat use, it is unlikely that more force will be applied than anticipated.

Arnold said that if the safety factor was taken sufficiently, it would be at a practical level.

Even human bones don't bend and break.

“Sure. All you have to do is foam this and lower the specific gravity.”

“We're going to be able to do that.Gin, Arnold, thank you! "

Eira asked Jen and Arnold to shake hands with a full smile.

"No, no, I'm glad I helped you."

Arnold called out to the cassette chair.

Um, Arnold-san, maybe there's something more you can use right now with this wartime technology?

Huh? Oh, I see.

Arnold, if you ask me, will be a strange face.

I'm also interested in Jin,

"That certainly seems to be the case."Let's summarize it into a report. "

and proposed that the ka-chair be very enthusiastic.

That's right! Let's get this together.

"I like cachaise like this, don't I?"

Ella reached the table with a bitter smile.

"Great, I'd love to hear it."

And Groma Trey.

Alright, let's get started.

Jin ruled and the discussion began.

Well, Arnold, let me ask you a question.

"...... but I can't think of anything... all of a sudden"

"That's true." What about alternatives to expensive or rare materials? ”

Arnold seemed to have something in mind when Jen designated him.

"Oh, there are two of them. One is Adamantite."

Huh?

Adamantite is the hardest metal in the world as a stand-alone metal, and it's heavy.

Because the output is small, the use is limited.... except Penglai Island.

"Harden carbon steel with 1.2% carbon, and multiply it with" "toughness" ""

I see.

"Toughening" is an engineering magic that increases the bonding power between molecules, so it hardens and improves toughness at the same time.

This would be about one-third to one-half of normal Adamantite.

"The specific gravity of steel is about 7.9, and the Adamantite is 19.3, so it is a substitute for strength per weight."

“That's right, this is useful!”

"Great."

Arnold seems relieved that he helped.

The other one is a magic crystal.

Ah, that's not going to be enough, is it?

"Yes, but I'll collect any scraps or powder or debris or remnants that were stuck to the stone."

I don't think that's one of them, right?

Ren can integrate by using "fusion" and "crystallization", and further improve the quality by "purification", but that is not possible for everyone.

In wartime, the main technology is something that can be used by anyone (as long as they are magicians (magic craftsmen)).

"Even if it's just one thing, use [Magic Resin (Magirezin)]."I'm going to use magic resin (magirezin) to harden these little magic crystals. "

Don't you use 'Fusion'?

"I don't use it.... Jin may not have noticed, but if you use" Fusion "normally, the crystal structure will be seriously disturbed."

"If you use [Crystallization]...... ah......"

That's right. Crystallization can't be used by ordinary magicians (magic craftsmen), can it?

Is that it?

"That's what it is."

I was convinced that that was what Arnold told Jen.

and listened to the explanation.
