The Influence of Thermo-Plastic Deformation on the Structure and Mechanical Properties of Powder Metallurgy Materials

  • Yu. V. Milman

Abstract

Powder metallurgy materials as a rule have porosity after sintering. Different pressure working processes (extrusion, pressing, forging, rolling etc.) are used to decrease porosity. Pressure working leads not only to consolidation of materials, but to changes in structure and substructure of materials, i.e. to variation of grain size and formation of dislocation substructure as well.
