Porosity has the greatest single effect on the response of PM Steels to heat treatment compared with conventional steels. The majority of parts have a porosity between 5 and 15 vol%, far more than is found in a typical casting. Every mechanism in press and sinter is subject to diminishing returns; i.e., compact density has a decreasing dependence on compaction pressure, as does sintering and homogenization.
