摘要

The influence of the fraction of the powdered waxy material to be compacted and the holding time under load on the residual stresses and the elastic response of the compacts is studied. The elastic response is experimentally found to be minimal in the compacts with a porosity of 7–12% at residual stresses less than 0.02 MPa in the compacted material.
