Micromechanics of Diffusional Creep

  • A. U.S., HAZZLEDINE

Abstract

Abstraet-ln polycrystalline materials at high temperatures and low stresses, creep occurs mostly by the diffusion of vacancies through the grain bodies and over the grain boundaries. A continuum theory of vacancy motion is considered to analyze diffusional creep on a microscopical level. A linear version of such a theory was formulated by Nabarro, Herring… (More)
