Actually when the molecules align, the metal becomes softer.
When you quench something, you cool the molecules, and the rate at which you cool them and the starting temperature determins the dissarray (maybe the word entropy would work here) of the molecules when solid, which determines the hardness/strength.
I think you are talking about metalic glass, which is pretty experimental right now. They take a thin film of hot metal, and cool it so quick that the molecules can't for grains; the molecules are more of a ceramic or glass or liquid (depending on how you wanna look at it) arrangement. I think the only application they consider for it right now is a golf club head.
Or, you could be thinking about turbine blades that they annel forever such that they form one grain of material, which is pretty cool, but not a process that would do anygood for a already existing prechamber.
