Abstract
Abstract Amorphous metal alloys are prepared from compositions in the beryllium-titanium-zirconium system. The compositions, in the form of long, continuous ribbon, are defined within an area on a ternary diagram having as its coordinates in atom percent beryllium, atom percent titanium, and atom percent zirconium, the area being defined by a polygon having at its corners the 10 points defined by A. 40% Be, 58% Ti, 2% Zr B. 35% Be, 57% Ti, 8% Zr C. 30% Be, 55% Ti, 15% Zr D. 30% Be, 20% Ti, 50% Zr E. 35% Be, 0% Ti, 65% Zr F. 45% Be, 0% Ti, 55% Zr G. 55% Be, 15% Ti, 30% Zr H. 55% Be, 20% Ti, 25% Zr I. 50% Be, 35% Ti, 15% Zr J. 43% Be, 53% Ti, 4% Zr.
