Estimating the surface tension of grain boundaries in pure metals

Abstract

The surface tension of grain boundaries with liquid-like structure in a pure metal is presented as a function of the melting temperature and the molar volume of the metal in the solid state at the temperature of melting. Several empirical expressions for estimating the average surface tension of high-angle GBs at high homologous temperatures are proposed on this basis.
