Vitreloy (Amorphous Metal Glass)

Zirconium-based amorphous metal glass with ultra-high yield strength.

Core Principles & Analysis

• Vitreloy 1, developed at Caltech in 1993, was the first metallic glass castable in centimetre-thick sections at cooling rates near 1 K/s.
• With no crystal lattice or dislocations, it springs back elastically to about 2% strain, roughly double that of conventional crystalline alloys.
• Bulk metallic glass flew on NASA's Genesis spacecraft as solar-wind collector material and reached consumers in Liquidmetal golf club heads.
