Numerical calculation of Kirkendall deformations and stress distributions in thin-sheet diffusion couples

Research output: Contribution to journalConference article

Abstract

We have developed an algorithm and a computer program to solve the coupled equations of diffusion and deformation. These equations can include the stress gradient effects and the pressure dependence of the diffusion coefficients (mobility effect) as well. The procedure is based on a finite element decomposition of the diffusion couple. Simulations were performed for thin sheet diffusion couples using a wide range of material parameters. The main features of the experiments (strong bending of samples accompanied with a decrease of the Kirkendall shift) were reproduced.
