초록

Ductile, strong, and stable (crystallization temperature above 250°C.) Al-X-Z metallic classes contain 90 at. % Al where X-Fe, Co, Ni, Rh; Z-rare earths, Hf, Y, Stable (crystallization temperatures reaching 500°C.) Al-Y-Fe-Si glasses have superior hardness properties upon consolidation. The present alloys are at least twice as strong in tensile strength as the strongest commercial aluminum alloys.

대표
청구항

A metallic glass aluminum based alloy of the formula Al85-90 (X,Z)15-10 where X=Fe, Co, Ni, Rh and Z=rare earths, and Hf, wherein the alloys are formed by arc-melting the elements in an argon atmosphere and forming the melt in a helium atmosphere and rapidly cooling the alloy to produce a single-phase amorphous aluminum rich alloy with high flexibility and high strength.
