Pressure sintering by power law creep
Abstract
During the pressure sintering of a powder compact, one of the more important contributions to densification is that of power-law creep. We calculate first the contribution of power-law creep to final stage densification; it is modelled by considering the voids as spherical holes surrounded by thick spherical shells of solid material which flow by power-law creep. The result gives a plausible explanation of the experimental observations of Urick …
