abstract = {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.
