Breakthough Makes Transparent Aluminum Affordable

Posted by Soulskill on Tuesday April 28, 2015 @08:10AM from the hello-computer dept.

frank249 writes: In the Star Trek universe, transparent aluminum is used in various fittings in starships, including exterior ship portals and windows. In real life, Aluminium oxynitride is a form of ceramic whose properties are similar to those of the fictional substance seen in Star Trek. It has a hardness of 7.7 Mohs and was patented in 1980. It has military applications as bullet-resistant armor, but is too expensive for widespread use.

Now, there has been a major breakthrough in materials science. After decades of research and development, the U.S. Naval Research Laboratory has created a transparent, bulletproof material that can be molded into virtually any shape. This material, known as Spinel (magnesium aluminate), is made from a synthetic powdered clay that is heated and pressed under vacuum into transparent sheets. Spinel weighs just a fraction of a modern bulletproof pane.

  Before we ask for this for windshields, we need to see how well it handles regular abrasive friction and small particulates. If it scratches easily then it may require a coating of glass on either side for its hardness (albeit with brittleness) in cases where security needs to go along with aesthetics, like armored car windows and other security windows, such that the owners don't care what happens to the glass layer in an incident but want it to look good before the incident and to remain intact during such incidents.
  
  I doubt that this will be, by itself, a windshield, and if a windshield made out of this stuff still needs a glass layer, then you're right back to where you were before as far as chipping with debris over a certain size is concerned.

  Indeed -- the last thing I want are shards of something with a hardness of 7.7 and razor sharp edges flying around. Think obsidian arrowheads, and then think of something that'll hold an edge even better.
  What I'd like to know about is how flexible the stuff is. Usually, the harder a material is, the more rigid it is -- which means that it is super hard right up to the point where it can't take the stress, at which point it fractures all over the place.
  Safety glass gets around this by 1) being pretty flexible and 2) being a laminate of hard and soft materials, so that when the hard material shatters, it is still bonded to enough of the soft material to avoid (many) sharp edges.
  I wonder what the behavioral properties of a laminate of spinel and lexan would be....

  The article says it is harder than glass but even if it was unsuitable for the outside layer, there is no reason it would need an inside layer of glass.

  Which kind of safety glass?
  They were talking about windshields, those are laminated glass. That means you have two sheets of ordinary annealed glass (which DOES break into big, dagger-like sharp pieces) with a plastic sheet in between (which prevents those sharp pieces from going anywhere). Presumably, given an appropriate substrate, you could make laminate out of any glass-like sheet.
  The other kind of safety glass is tempered. This causes the glass to be stressed along the edges so that when it does break, it breaks into a million tiny pieces (all of which are very, very sharp). It may also simultaneously pop, especially if hit along the edges. It's less dangerous because the pieces, while sharp, are simply too small to do any real damage even if, say, a piece explodes while you're holding it.
  Source: I worked for a cut & temper operation, I've dealt with all kinds of glass.

  Of course, given that a big sheet of something like Sodium (#6) would probably be pretty damn expensive, I suspect that the abundance of the material's constituent elements is not necessarily the biggest factor in its price.

  To decrease shards you only really need a film coating of something elastic. Simple 3mm glass coated in that way won't stop a bullet but the film will keep the glass shards in the frame and not flying in your face. That doesn't matter much if the bullet kills you but in this case a 1mm thick coating could probably prevent shards effectively while the Spinel stops the bullet.

  Transparent aluminum like this stuff is basically sapphire/aluminosilicate glass. So it's a lot like pyrex except especially scratch resistant and hard. It's no more bendy than any other kind of strong glass material, and will shatter into big stabby pieces if stressed enough, although in their vacuum powder-sintering process, it looks like it might be more prone to chipping and ablating than outright shattering, since it's basically a wad of microscopic granules of glass melted together at the edges instead of a single piece of glass that was formed from continuous liquid.

It is my understanding the presidential limo has armoring and windows that can stop a 50 caliber round, it also weigh like 12 tons. And just about nothing short of a tank can stop 2 inch or larger rounds.
  Once you get up to the 6-12 inch rounds there isn't much of anything that can stop them but the solution I mentioned above. Once you are up to that size the energy that needs to be stopped is just beyond what most materials can withstand.
  Armoring is constantly evolving to increase resistance but nothing is bulletproof. Not the vest the cop is wearing nor the cars sold to heads of state.

  It's hard enough to be scratchproof to the vast majority of things we encounter in our daily lives. Once you're harder than quartz and tool steel, there's not much you'll encounter in normal circumstances that can scratch you.
  It's really not the spinel aspect that I find neat. It's the blurb about their process. They say they got it to work by two things: one, extreme purity (no surprise there), and two, mixing. No matter how well you try to mix fine powders together by any normal means such as shaking, you're never going to get a perfect mixture where all of the particles pack down together to their optimally dense arrangement. Apparently they've come up with a process that allows just that (they don't go into details).
  Well, that's worth far more than spinel. Cheap and scalable production of materials comprised of perfectly arranged microstructures? It seems like such a thing could things in every field of materials science, from batteries to superconductors.
  If, that is, it lives up to how the article makes it sound. TFA is rather high on hype and short on details.

(For shorter ranges, the shells would have the penetrating power to get through the side armor. For longer ranges, the shells would be coming down sufficiently close to vertical to penetrate the deck armor, which could not be as thick as the side armor.)
  I've read that there were precisely six pieces of armor afloat that a 16" shell couldn't penetrate at any range: the front turret armor of the Japanese battleships Yamato and Musashi. These were about two feet thick (which a 16" shell could get through at close range if the shell hit the armor at a right angle), and sloped at about a 45-degree angle.

  Oh, yea, that junk I could only really sit though once... The best of the bunch was #2 and how that was made after the dreadfully made #1 is a testament to the draw of the franchise. After #2 it was down hill, no matter what the director. The stories where junk, the premise of each worse. About the only thing that advanced was the special effects.
  BTW, my complaints about Nimoy are really "tongue in cheek" as is my critique of #4. Where it's not the best effort in the franchise, I actually liked it as a movie. And that's saying something because I was a projectionist at the time and I saw that movie multiple times a week for the bulk of it's time in theaters.
  Shatner can't act OR direct though... But it happened that his single character fit his personality pretty well for the most of his career so he got by.

  And how much care tending did they actually do between hauling ass to the Sun and back to Earth?
  Seeing as how they only traveled in time with one round trip, this question is senseless. Instead you should ask what would Mr. Scott want to plan for? Would he want to verify the whales are safe after beamup? Yes. If the sensors inside showed the whale in distress would he want to at least make a visual account of it? Yes. Would the transparent tank be better for them to have if the time travel jump failed and they were stranded? Yep.

Bullet proof, maybe not machine gun proof by laughingskeptic · 2015-04-28 09:16 · Score: 2

Like many ceramics they note that it chips rather than breaks. So you could "chip away at it". Also the material very likely has an impact stress point beyond which it will explode when impacted. So it is bullet proof up to a point. They say that it doesn't need to be layered, but in practice I'll bet they layer it with Kevlar or a similar material with complementary properties.

  Great answer, except for the Kevlar part. Safety glass and "bulletproof" glass already work this way, except you don't use Kevlar. You use plastic, not sure what type.
  The plastic creates a discontinuity in the glassy material. If the hard but brittle glass shatters, the shatter lines stop at a plastic layer (in really fancy systems you have multiple layers). The plastic also helps hold the material together under failure conditions, reducing shrapnel wounds at time of impact and danger to bystanders afterwards.
  The layering concept has wide applicability. There are reports of high end tank armour using layered ceramics and steel going back to the 1970's.

7.7 mohs hardness? by jolyonr · 2015-04-28 13:42 · Score: 1

The Mohs scale of hardness is a relative unitless scale comparing things to ten common minerals. There is no '7.7' on this scale. 7 is Quartz and 8 is Topaz. So all you can say with any accuracy is that it is between 7 and 8. Maybe it is closer to Topaz in hardness than Quartz, but even so, there's no way of calculating a '7.7' so they just pulled that number out of their ass...
Which makes me wonder how accurate the rest of what they say is.

  It is also comparing things to OTHER things that fall between the two points. Something is not just "between 7 and 8", it is also harder than some other materials "between 7 and 8" and softer than others. The number after the decimal allows for them to be rankedrelative to one another. What you're saying is that just because the code base of Software 5.0 and 5.1 are largely the same there is no way to distinguish between them, and that everything in the 5.x line except 5.0 itself is merely "between 5 and 6".

  You're wrong in two different ways, which I kind of admire :)
  Firstly, you have something that is between 7 and 8, so for arguments sake you call that '7 and a half' (this is regularly done).
  Then you take another sample, and that scratches the '7 and a half' pieces, and not the 8, so it's between 7 and a half and 8. But that's a completely different scenario to arbitrarily assigning a '7.7'
  There is another method of measuring hardness, the vicker's system which does indeed follow a linear scale, so you could potentially use the vicker's hardness of the specimens to determine an approximate decimal value for the hardness of your chosen sample. But that's completely stupid because the whole POINT of this is to show a relative hardness between two samples, ie to be able to measure it by scratching one piece against another. So my comment stands, the '7.7' value is pulled out of someone's ass and has no scientific merit.
  The second problem is you then compare with software revision numbers... which are of course numbers pulled entirely out of someone's ass. And of course, version 5.9 is usually less than version 5.10 etc. so again you have no way of saying 'version 5.5 is about half way between version 5.0 and version 6.0 in features.'

  Version numbers are arbitrary, I never said they weren't. Yes, the decimal is a divider and not a mathematical decimal, so 5.10 comes after 5.9 where it can't in the hardness scale. I never said anything about "half the new features". In fact I'd a expect large gap between the last 5.x and 6.0 and not assume the version numbers meant anything in regards to the actual quantity of features, only about their timing. That is, if a feature is introduced in 5.2, it's probably still going to be there in 5.5 (unless it was fundamentally broken and had to be yanked).
  The decimals on the Mohs scale seem arbitrary as well, but that does not make them meaningless. If you have just one substance between 7 and 8, you could justifiably call it 7.5, but what do you do if it turns out that everything else between 7 and 8 scratches it? You downgrade it to 7.1, that's what. These are like old BASIC line numbers where you assign them in the hopes that you don't have to change any later because of things you plug in, but sometimes you're wrong.
