High strength amorphous aluminum-based alloy and process for producing amorphous aluminum-based alloy structural member

摘要

A structural member is produced from an amorphous aluminium alloy by compacting at a temperature at least 40 DEG C below the crystallization temperature to form a green compact of at least 80% density. The amorphous aluminum-based alloy may comprise 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 layer volume fraction (Vf) of at least 50%.
