| Abstract |
Various yield criteria for describing densification and deformation processes of powder compacts and sintered metals have been reviewed and compared with a yield criterion proposed by the present authors. Various parameters involed in the criterion have been discussed. The yield criterion satisfies experimental yield curves from combined tension and torsion tests of sintered porous iron specimens. |
