It is called metallic glass, or amorphous metal and is being touted as revolutionary to the field of metallurgy. It is much stronger and lighter than titanium and CAN BE INJECTED MOLDED as well, eliminating the need for machining. It can be used to make anything from fighter planes to bicycles and would definitely have aerospace ramifications. It is already on the market and is being used in golf clubs and transformers. It does have a major drawback however, it is very expensive as you might have guessed. Cryogenics must be used to rapidly cool the metal to get the metal glass effect without the crystals. They have just recently found a combination of alloys that don't need to be cryogenically cooled to form the amorphous metal. This could be a breakthrough that would make the process more economically competitive.

I wonder what application this material might have in engine technology?
