Abstract

In order to develop the atomic mobilities for the fcc phase of the Co-Cr-Ti alloys, interdiffusivities were determined with diffusion couples annealed at 1323 K for 100 h, the results of which were then critically assessed using the DICTRA software. From comprehensive comparisons between the calculated and the experimentally measured diffusion coefficients, good agreements can be obtained. The obtained atomic mobilities for fcc Co-Cr-Ti alloys are further verified through numerically simulated concentration profiles in diffusion couples, where the kinetic characteristics can be fully reproduced.
