Yale University boffins have devised a new way of identifying super strong metallic glass alloys that will "drastically" increase the discovery rate of the "potentially revolutionary" materials. Scientists are currently rushing to classify various complex alloys known as bulk metallic glasses (BMGs) from a a "vast compositional …
Apple off my eyes
I hope they are patenting all these creations before Steve J...oh-errrr
Am I missing something?
So they've sped up the process by doing 3000 tests in parallel, and by using very small samples?
Ooh, revolutionary thinking there!
Re: Am I missing something?
Yes, you are.
While I was having a crap yesterday, I had an idea about using nanotubes to make a new class of super-light, super-dense batteries. I must check to see if I'm a millionaire by now.
This may come as a surprise, so sit down: The mental and physical effort required to conceive an idea isn't even a tiny fraction of the effort needed to bring it to reality.
One known metal glass combination, a scandium/yttrium one, would make, in theory at least, the world's finest golf driver.
Materials cost, before manufacturing, would be around $1,000 for it though.
El Reg's friendly neighbourhood rare earths spiv.
Curious what would make it a finer material for a driver than Titanium? Given that the USGA and R&A limit both the coefficient of restitution of the driver face, as well as the overall volume of the head, it doesn't seem as though there's any room for more advanced materials to improve over the current state of the art.

Which still won't stop you slicing it into the rough...
I'm used to abstracts actually *telling* me what the reports about.
The core problem is not that bad. for a 3 element alloy (94 elements)^3
But now multiply the percentages to give (94 * 100)^3
Is is a physical strategy?
Is it a clever hack on the quantum mechanical calculation algorithm?
And BTW yes I think you could find some Merkins who'd pay $1000/club.partly because a) they really want to play good golf and b) Because they can.
Of course if that discovery process was skewed to start with the cheaper elements.....
Re: I'm used to abstracts actually *telling* me what the reports about.
I can't believe they will go manually through every possible combination.
With normal alloys you usually step through enough points to identify the key transitions and then draw a phase diagram by interpolation. You can then roughly predict properties of specific alloys by placing them on the diagram.
For metallic glass they use additional analytics to predict Glass Forming Range, which presumably can then be tested with a few additional data points...
So, on the horizon
(Can't believe no-one has already mentioned it)
Re: So, on the horizon
We already have transparent aluminium. It is also known as artificial sapphire. It is just a particular crystal arrangement of aluminium oxide.
Re: So, on the horizon
All you have done is beaten us to it
Remember to wear knickers
So is my flying car is going to be made of glass?
Re: Remember to wear knickers
That would make the VIP arrivals at the Oscars a must-see. Mmm, Mila Kunis. [Judy Dench, not so much]
And here was me thinking...
they were going to test new materials through computer modelling/simulation first.
Is that not possible in the 21st Century?
Re: And here was me thinking...
You can only model what you know.
What if one of these combinations does something 'odd' that you weren't expecting and couldn't reasonably have predicted?
Cup of tea anyone?

"The most exciting phrase to hear in science, the one that heralds new discoveries, is not 'Eureka!' but 'That's funny...'" - Isaac Asimov
I was under the impression materials science had stepped out of the foundry and into computer modelling. In the way Dmitri Mendeleev managed to accurately predict the properties of yet to be discovered elements way back in 1875, I would have thought our ability to combine elements and molecules in a computer model and assess their qualities would be here by now. Obviously I am wrong, but what on Earth have these muppets been up to for the last century, if they haven't come to some defining conclusion about how matter interferes with each other and coded that into a ZX Spectrum.
Massively impressed by their engineering skills, but come on, let's get all 21st century on this one.
I throw down my gauntlet and challenge the scientific community to get their act together and come up with a program that allows me to enter a list of properties that I desire in a material and it churns out a list of credible molecular combinations that meet that specification. I guess this will need the power of quantum computing, but for Christ's sake get a move on will you, the Earth is being consumed to make substandard inefficient crap and we desperately need an intelligent way forward.
I'll buy the winner a beer.
P.S. After I buy AC one for beating me to it. I shouldn't have had a coffee break.
"Metallic glass" bones eh?
I just had a hip replacement. It's lead crystal. Bugger.
PS: This is just a joke.
Looking at some of the diagrams it looks like
They make up graded alloy strips where one or more of the elements varies along the length.
The strip is then laid on top of what looks like a plate with holes in it. At this point I'd guess they put the whole lot in a furnace and connect it to a high pressure supply.
They then try to blow bubbles with the metal.
Biggest bubble seems to win.
BTW I suspect the problem with quantum chemical tests is 1 simulation will take hours and the effect is (I suspect) non linear, so extrapolation does not work.
Order!!...Order I say!!
