Easy-to-Make Material Scratches Diamond

holy_calamity writes "A material tough enough to scratch diamond that can be made without resorting to massive pressure has been developed at UCLA. A regular furnace and a zap of current is enough to meld boron with the metal rhenium." Sound familiar? This is the other new material tougher than diamond, but no word yet on how they rate against each other.

IMPOSSIBLE! (4, Funny)

Anonymous Coward | more than 7 years ago | (#18823569)

Diamond is one of the hardest (if not THE hardest) metals known to man!

Due to extensive research done by the Fourchon University of Science, diamond has been confirmed as the the hardest metal known the man. The research is as follows.

Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed.

They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an out into the wall, and the wall came out fine.

They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors.

They crashed 400 miles per hour into a diamond traveling at iron car. Western New York was powerless for hours.

They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards midwestern Prussia at 400 billion miles per hour.

They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused two wayward airplanes to lose track of their bearings, and make a fatal crash with two buildings in downtown New York.

They spun 400 miles at diamond into iron per wall. The results were inconclusive.

Finally, they placed 400 diamonds per hour in front of a car made of wall traveling at miles, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known the man.

Badly. Bullets should be (a) heavy, and (b) tear apart easily. That way they (a) contain lots of kinetic energy, and (b) rips the target to pieces.

Military ammo usually lacks quality (b) because it's better to disable an enemy soldier than to kill him, both for the psychological effect at the enemy, who has to watch him suffer; and because his buddies will be busy rescuing him instead of fighting. Oh, and because the Geneva convention says so, they seem to think it's somehow more "humane" to cripple soldiers than to kill them.

Re:Obligatory... (2, Informative)

Anonymous Coward | more than 7 years ago | (#18823807)

Wrong. The use of hollow point and similar ammo during times of war is restricted by the Hague convention of 1899, not the Geneva convention. Also note that tumbling and frangible full metal jacket ammo is allowed, such as British mark 7 .303

No matter how much (a) it has, if it is hard enough, it will strip the rifling grooves right out of the barrel, and won't hit worth crap. A bullet isn't supposed to be hard. Unless we're talking about the Penetrator of a Discarding Sabot round.

Oh, and because the Geneva convention says so, they seem to think it's somehow more "humane" to cripple soldiers than to kill them.

God, I wish this dumb myth would die.

First: there is no infantry weapons system (other than the "NLW" which are designed for crowd control, not combat) specifically intended to cripple rather than kill an enemy. One shot, one kill, is always the infantryman's goal. The best possible way to remove an enemy soldier from the fight is to kill him; wounded enemies often can and do keep shooting back. The "wounding is better than killing" meme is often repeated among soldiers as well as civilians, but it does not appear anywhere in Army doctrine.

Second: the LOAC's prohibition on "dum-dum" rounds is basically intended to make things easier on military surgeons; it's a matter of what's humane off the battlefield, not on it.

Third: FMJ rounds, as opposed to the wide variety of other types of rounds which would be acceptable under the LOAC, are used primarily for reliability and versatility. Reliability, because rounds with any exposed lead will foul a rifle under typical infantry combat conditions (dirt, mud, sand, and enormous volume of fire between cleanings.) Versatility, because softer rounds are better for use against unarmored human targets, but that's about it. Trying to stop a vehicle with soft-nose rounds? Good luck. And modern body armor is very very good, but you've still got a good chance of getting through it with a dead-on shot from a rifle of decent caliber if you're using FMJ; soft-nose will just go splat.

Re:Obligatory... (1)

The_Wilschon (782534) | more than 7 years ago | (#18824183)

We already know how to make metals that are much harder than those we make bullets out of. Problem with hardness is that along with it usually goes brittleness. Ever try to use a diamond to scratch glass? It is quite likely to shatter under your fingers. Hit two hardened steel tools together? Bad news, there is a strong risk of either sharp bits flying off, or one or both tools shattering completely.

I'd imagine that a bullet as hard and as brittle as diamond (or more so) would likely shatter before it even left the barrel. So instead of one piece of matter with a ton of momentum coming at you, you'd have a lot of tiny shards, each with not much momentum, and thus each one much more easily stopped by body armor, or even just clothing.

OTOH, I don't know that this new metal they are describing is exceedingly brittle. It might not be.

Right, i remembered wrongly. Much energy was spent in the comments on explaining the difference between stiffer, harder, tougher, etc., because many posters got it wrong.

Hardness, stiffness, and toughness (5, Funny)

Dr. Stavros (808432) | more than 7 years ago | (#18823787)

Again, we mustn't conflate hardness, stiffness, and toughness!

I've been studying diamond for a while now, and have a fairly prominent webpage about diamond's material properties [sque.co.uk] , and on three separate occasions I have been contacted in the following way:

A budding fantasy author is writing a book in which the protagonist has a sword made out of diamond, "because diamond is the hardest material of all!", and they wanted to run the idea past me first.

So I point out that, despite being very hard (i.e. resistant to indentation), diamond is in fact very brittle (i.e. not very tough), and indeed the very first time that our hero hits something with his diamond sword, it will shatter.

In one case, the author said that I had basically ruined his life by wrecking the whole concept of the book that he had been writing for the last few years. In subsequent emails, he was begging me to come up with a solution (e.g. diamond sword, coated with steel, etc.?)...

onedotzero (926558) | more than 7 years ago | (#18824475)

Something like that, yes. I'm not sure of the metals used, but one is softer than the other. This also gives the katana its trademark curve, as one metal contracts sooner than the other as they cool.

Re:Hardness, stiffness, and toughness (1, Informative)

Anonymous Coward | more than 7 years ago | (#18824823)

Katana are forged from steel, not different metals. How the steel is quenched gives it a different properties. Pearlite (soft, flexible) and martensite (hard, brittle) are steel which is cooled at different rates, and to use these properties, katana are painted with layers of clay before quenching. The curve happens because of the different cooling rates of the steel because of the clay.

(I guess steel would not be exotic enough) (d) If the book gets ruined because the plot evolves around a diamond sword. Mmmh. I dunno, but usually a book is built upon a good story, not a flashy gadget. He might want to reconsider that part as well...

He's a writer... he should come up with something.

The sword was crafted by an Uber Death Mage, who used the blood of the last virgin to scream "first post!" on slashdot to cast a technobabble spell, which caused the entire blade to form as a single facet of diamond. Thus having no stress points, the blade would be nearly perfect, as long as the victim didn't use a Google shield to find previous postings and block it.

That took me a whole 15 seconds.... surely he's had a bit more time to ponder?

Re:Hardness, stiffness, and toughness (2, Informative)

Kjella (173770) | more than 7 years ago | (#18824207)

Something tells me the author won't be very successful if he can't write himself out of that corner. Even if it was possible, would you in a fantasy novel explain it's a diamond-steel alloy with micrograin and internal stress? Any of the following should work:

a) The sword is magical. If it's that central, it should be anyway and so it's the magic making it indestructable, not the material
b) The sword isn't actually of diamond, but the material is unknown and looks like it, so it's been given a poetic name
c) It's been created in a magical forge or forger, and doesn't have the properties of diamond (sorta a) but less emphasis on the sword's power)
d) In the hands of the wielder, it changes power (something along the lines of the power flowing through it)
e) Don't actually explain why, it's fantasy after all

Certainly a) and b) should be trivial to implement. After all, I assume he must have taken more than a few liberties with reality already to explain how a diamond sword came into being.

You should get him to send you a sample of his writing - the giggles might make up for having to put up with him. (I would never condone posting a link to it. Naah. Never. ;)

If it's a fantasy world making copious use of magic, real-world physics need not apply--the author should be able to whatever they want as long as it's plausible in the story's canon. Sheesh.

In subsequent emails, he was begging me to come up with a solution (e.g. diamond sword, coated with steel, etc.?).

How about the good old deus ex machina, it worked for the ancient greeks. Just let one protagonist say something along this line:
"thanks god they invented the nanofluxdiaconplexor, which transforms diamonds into the toughest material in the universe!"

problem solved.

Eh, tell them to throw in an extra chapter about how he found or somehow acquired a sword of true damascus steel. Then in the word file, just have them replace 'diamond' with 'damascus'. I'm sure that sword would do good enough.

Headline is wrong... (1)

Yup, this new material scratches diamond, but from the article:

The material is nearly as hard as cubic boron nitride and boron suboxide, two of the hardest materials known, and like them can scratch diamond. It should also be able to cut steel without reacting chemically with the iron.
Ideally the headline should be mentioning that it's a material created in a furnace without using expensive high pressure methods. That's what makes this annoucement special.

Maybe that's why the title is "Easy-to-Make Material Scratches Diamond".

Think the parent maybe right - I'm pretty sure it read "New Material Scratches Diamond" earlier.

For Gawd's sakes please there is nothing wiereder than hearing self proclaimed "nerds, geeks", call diamond a metal dude its made of carbon, a NON METAL and thus cannot be a metal please. I know this might be redundant but then constant repetition is required to get the point accross it seems.

If it could be incorporated into a matrix of buckytubes, it could be a great laminating material for armor.
