Abstract

New aluminum-based amorphous alloys were found to be formed in Al-Y-M and Al-La-M (M=Fe, Co, Ni or Cu) ternary systems by melt spinning. Their compositional ranges are 3 to 33 at%M and 3 to 22 at%Y or 2 to 18 at%La. The alloys containing more than about 80 at%Al havegood bend ductility. The crystallization temperature Txincreases from 414 to 831 K with an increase of M and yttrium or lanthanum contents. The effect of the solute elements on Txis interpreted to be dominated by the attractive interaction between aluminum and M, yttrium or lanthanum atoms.
