Abstract
A high strength amorphous aluminum-based alloy comprises 75 atom % (inclusive) to 90 atom % (inclusive) of Al; 3 atom % (inclusive) to 15 atom % (inclusive) of Ni; and 3 atom % (inclusive) to 12 atom % (inclusive) of at least one element selected from the group consisting of Dy, Er and Gd, and has an amorphous phase volume fraction (Vf) of at least 50%. This leads to a higher amorphous phase forming ability and a wider plastically workable temperature region so that the workability of the alloy is satisfactory to produce structural members utilizing a working process such as a hot extruding process, a hot forging process or the like.
