Abstract:
A production method for an aluminum-based alloy comprising the steps of:a) selecting an element Q, which is at least one element selected from the group consisting of V, Mo, Fe, W, Nb, and Pd;b) selecting an element M, which is at least one element having an atomic radius which is more than 0.01 .ANG. larger or smaller than the atomic radius of said element Q and which is selected from the group consisting of Mn, Fe, Co, Ni, and Cu;c) preparing a liquid-melt consisting essentially of Al having an amount in atomic percentage of 100-(a+b), said element Q having an amount in atomic percentage of a and said element M having an amount in atomic percentage of b, wherein said a and b satisfy the relationships 1.ltoreq.a.ltoreq.8, 0<b<5, and 3.ltoreq.a+b.ltoreq.8, said liquid-melt not containing rare earth elements; andd) quick-quenching said liquid-melt to obtain a solidified aluminum-based alloy having a metallographic structure incorporating a quasi-crystalline phase.
