Abstract

The thermal and mechanical properties of 1 mm diameter rod specimens were investigated over a wide composition range of the Cu-Zr binary alloy system. Our results indicated that alloys with composition near Cu-36 at.% Zr have a higher activation energy and a lower plastic deformation during compression test than those of compositions near Cu-50 at.% Zr. A relationship between the activation energy and the plastic deformation could be worked out suggesting that the lower is the activation energy to crystallization, the larger is the plastic deformation.
