Theory of the Method for Determining the Diffusion Coefficient at Grain Boundaries (K Teorii Metoda Opredeleneya Kozffitsienta Diffuzii po Granitsam Zeren Metallov)

摘要

A strictly mathematical basis for determining the grain boundary diffusion coefficient is developed. It is based on the model of Fisher (Jnl. of Appl. Physics 1951, 22, 74). An equation for the grain bdy. diff. coeff. is given along with the necessary boundary conditions for its application.
