Abstract

Germanium-silicon alloys of the composition Ge30Si70 have been prepared by hot pressing powder compacts at temperatures between 1300 and 1493 K (the solidus temperature) at pressures up to 40 MPa. The densification of the compacts was observed as a function of time. For each temperature and pressure an end-point density less than the full density was found. The time-dependence of the densification and the pressuredependence of the end-point density can be described empirically in terms of a plastic flow mechanism.
