The Effect of Grain Size on Thermal Diffusion in Metals.

Abstract

This research was concerned with evaluation of the segregation of substitutional solutes in metal alloys resulting from the application of a temperature gradient. Metallurgical structure, namely grain size, is known to be an important factor in solute redistribution. Measurements were made to evaluate the influence of this parameter. Namely, it has been shown that grain size controls the non-equilibrium concentration of vacancies which in turn influence solute fluxes. (Author)
