摘要
The invention is directed to microcrystalline Al-based alloys produced by annealing an alloy formed initially in a substantially amorphous state by rapid solidification (about 104 K/sec) and having a composition consisting essentially of, in atomic %: from 5 to 30% Si from 11 to 22% Ni wherein the Ni may be partially substituted by Fe up to 10%, by V or B up to 5 atomic % each, or totally substituted by Mn up to 22 atomic %, and wherein Fe+Ni+Si/=42%. In the microcrystalline state, in the vicinity of the first crystallization peak, there is a metastable hexagonal phase whose crystalline parameters are about a=0.661 nm and c=0.378 nm.
