Abstract (en)

[origin: EP0561269A2] An amorphous alloy material consisting of a principal element and other additive elements and containing fine grains of perfect crystals having an average particle size of 2 to 100 nm that are formed by self-control and dispersed in an amorphous alloy matrix; and a method for self-controlling the average particle size of the crystal to be in the range of 2 to 100 nm through the stable phase of the amorphous phase or the stability corresponding to precipitation treatment temperature in the amorphous matrix by heating the amorphous material. Examples of the principal element include Al, Mg and Ni and those of the additive elements include rare earth elements. The alloy material has superior mechanical strength and toughness and exhibits precipitation-induced plastic flow. <IMAGE>
