Abstract

Amorphous alloys in the Mg–Pd binary system were formed in a composition range of 10 to 35 at%Pd by melt-spinning technique. The crystallization temperature and tensile strength of the amorphous Mg100−xPdx (x=10, 20 and 30 at%) alloys are in the range from 417 to 535 K and 440 to 650 MPa, respectively. There is a tendency for the crystallization temperature and the tensile strength to increase with increasing Pd content. Vickers hardness also increased with increasing Pd content. Their compositional dependence is attributed to an increase in the number of Mg–Pd atomic pairs with large negative mixing enthalpy. Crystallized structure of the Mg–Pd amorphous alloys was also examined in correlation with equilibrium phases.
