Abstract

For the densification of metal powder compacts during sintering, in the stage of intensive shrinkage (as also for the steady-state high-temperature creep) a Nabarro-Herring mechanism is assumed, as a rule1. Due to the capillary pressure, vacancies are emitted from the pores and absorbed by the grain boundaries. The pores are filled up by an equivalent, but oppositely directed flow of atoms. In the classical experiments by Alexander and Baluffi2 this process of material transport was demonstrated.
