This research is to investigate the deformation characteristics of sintered compacts and the evolution of voids in the forging process under di erent frictional conditions. The Gurson-Tvergaard yield criterion was used to describe the plastic behaviour of porous materials, while the material paramet
The mechanical properties of powders at high pressures are difficult to measure and therefore such data are rarely reported in open literature. Available test equipment mainly operates in the low-pressure region, 0-200 MPa. Calcite (CaCO 3 ) is a mineral suitable for high-pressure processes, e.g. si
