The impure retardation of interparticle joining surface migration

Abstract

An analysis of migration of the interparticle joining surface in the conditions of impure retardation is presented. An expression quantitatively connecting retardation work with the initial segregation on a metal surface and temperature conditions of formation of hot-deformed powder material is derived. The values of retardation work are calculated when some types of iron powder are used as the initial material. .
