Abstract

Grain boundary and free surface tension for pure copper and copper-tin alloys are measured. On the base of these data isothermes of grain boundary tension, free surface tension and isothermes of adsorption are constructed in assumption of a dilute solution. Grain boundary diffusion coefficients of copper were calculated by using the relation of Borisov et. al. for copper and copper-tin alloys.
