Abstract
The influence of hydrostatic pressure (∼ 6.5 kbar) on the stress for plastic flow in a Pd77.5Cu6Si16.5 amorphous metallic alloy in compression and tension has been examined. The observed effect (δlnσ/δP ∼- 5×10−6 bar−1) is very close to that exhibited by crystalline metals. The highly inhomogeneous nature of the deformation appears to be unaltered by pressure. As at one atmosphere, failure in tension with high superposed pressure occurs by rupture through a zone of intense plastic shear. The fracture surface topography is strikingly different, however, because cracking inside the shear zone is suppressed in favour of crack initiation at its periphery.
