About Forecasting Durability of Particles of Iron Powders and Sintered Materials

Abstract:

Equations for an estimation of hardness and durability of materials of particles of iron powders in various zones are received. The opportunity of reception of materials with physicomechanical properties above separate zones of particles is shown. By development of technological processes of manufacturing sintered details with demanded physicomechanical properties it is necessary to know the physical characteristics of particles of an initial material, and sintered ensemble with them and their possible limiting values. However, definition of separate mechanical characteristics of particles is impossible because of their small sizes and complex form. Authors attempt to define strength and fluidity of various zones of particles of iron powders and sintered materials on their basis, using a method of microhardness testing.
