Elastoplastic deformation of sintered porous materials in pressure working processes

Abstract

The highest efficicеcy of stamping the powder blanks is obtained in producing axisometric components with a central cavity, large defenses in the cross section, and complicated external configuration. This large group of components includes sleeves, caps, and vessels with a blind or continuous cavity while are used extensively in various machine components. Cutting these components is associated with a high labor content, a large loss of metal in shavings, and the need to use complicated and expensive tools.
