Abstract

The pseudo-HIP method was applied to the hot compaction of two kinds of stainless steel powders with average particle sizes of 53 and 0.06 microns, respectively. The preheated powder preform, encapsulated in a glass tube, was compacted in a steel die using preheated alumina granules as a pressure-transmitting medium. The densification behavoir and microstructural development were investigated by varying compacting pressure and temperature. It has been found that full dense compacts with fine-grained microstructure can be obtained at temperature 300-400K lower than with normal sintering.
