AB  - Bulk samples of Pd41Ni10Cu29P20 glass were tested at constant true stress (20-636 MPa) in compression at 550, 555, and 565 K to study the transition from steady-state creep at low stress to deformation-induced softening at high stress. In the high-stress regime strongly accelerating creep was observed. All deformation was homogeneous. The activation volume was 106 Angstrom(3). The isoconfigurational activation energy was 9.03+/-0.64 eV. The disordering rate is proportional to the applied power density (stressxstrain rate). The disordering process is inefficient in energy and in the production of free volume. (C) 2005 American Institute of Physics.
