Liquid metal alloys

This company has been around for awhile, and it looks like they are turning the corner in commercializing their technology of metal alloys that behave like glass.

Liquid metal alloys can be injection molded, sprayed, and cast just like glass, and after cooling they remain amorphous. The lack of a crystal structure also allows a fine polish for optical applications. Apple Computer recently purchased exclusive rights to use this technology in consumer products, and the rumor is they plan to start molding product cases with these metals.

To create a glass structure the alloys must be rapidly quenched from the liquid state. Annealing for stress relive cause the alloy crystalize. I wonder it the residual stresses from rapid solidification would prevent accurate figuring.

They have been trying to enter the jewelery and other markets for many years. Their golf clubs got panned because of the Beryllium used in that alloy. It is pretty much a solution looking for a problem.
