Abstract

Glassy Pd41Ni10Cu29P20 was creep-tested in compression at constant true stress. The defect concentrations were shown to be reversible with reproducible kinetics. The results could be fit better with a defect creation rate that is proportional to the applied power density than with one that depends on the strain rate only. The dilatation mechanism for creation of free volume is inefficient in energy and generation of free volume.
