Abstract

A single shear test is carried out to characterize the shear failure of metal powder compact during powder compaction process. An iron powder and a stainless powder are tested and their shear failure enterions are investigated by an improved single shear test method devised by authors. Nominal friction coefficient at the shear failure plane of powder compact increases with increasing compact density, but it can be expressed without density dependence as a function of relative normal stress, where the relative normal stress is derived as the ratio with the normal stress and compaction stress. The differences of shear failure criterion in tested powder compacts are discussed with consideration on the influence of interparticle friction that depends on properties of powder.
