The case for bulk metallic glass

The last ten years have seen the discovery of amorphous metal alloys that are glass forming at cooling rates as slow as 1°C s−1 to 100°C s−1 in the bulk via conventional metal processing such as casting, but with the ease of molding of polymers. They are twice as strong as steel, have greater wear and corrosion resistance, are tougher than ceramics, and yet have greater elasticity. Increased plasticity in amorphous/crystalline composites now promises new structural applications.
