✦ Synopsis

Based on the formation mechanism of structural defects of amorphous metal-metalloid alloys prepared by melt quenching recently proposed by one of the authors, and from the viewpoint that there are no movable "micro-dislocation elements" in the small aggregates with chemical short-range order, a new microscopic mechanism that amorphous alloys possess high strength has been proposed. The strength of iron-based amorphous alloys has been specifically estimated by extrapolating the Bailey-Hirsch relation, and its order of magnitude is consistent'with available experimental results. Specific ways to increase the strength of amorphous alloys have also been discussed.
