GRAIN BOUNDARY DIFFUSION IN LEAD

Abstract

The purpose of this research was to investigate grain boundary self- diffusion in high purity lead and, specifically, to study the influence of orientation and impurity content upon this phenomena. Bicrystals of zone- refined lead were grown from the melt with various tilt and twist grain boundary orientations to study the effect of misfit. For the study of impurity effects, bicrystals with similar misfit were grown with lead containing varying amounts of the im purities tin, thallium, indium, and bismuth. Diffusion experiments were carried out using high resolution autoradiography and lead-210. Dif fusion coefficients were determined from the Whipple and Fisher diffusion models with the data of depth of penetration measurements.
