Abstract

Creep during sintering of CdO powder compacts was studied in a loading dilatometer by applying a small, transient, uniaxial load to the compacts. after the load was removed, the axial shrinkage rate was lower, but the radial shrinkage rate was actually higher than that of a compact sintered under no load. This reduction in the axial shrinkage rate is more pronounced for longer transient loading times. the results provide further support for a mechanism of simultaneous creep and densification in which creep at constant volume occurs by diffusion-controlled grain-boundary sliding.
