Al and Re Interdiffusion in the γ-Phase of Ni-Al-Re System
The activation enthalpies and frequency factors for interdiffussion of Al and Re in the γ-phase of Ni-Al-Re ternary system were estimated by a series of experiments using diffusion couples in the temperature range from 1200 to 1300°C. The method developed by Whittle and Green was applied to obtain the interdiffusion coefficients of the solutes (Al, Re) in the system. The activation enthalpies Q and the frequency factors \tildeDo obtained from the experiments confirmed the slower diffusion of Re than Al. In addition, it was found that the influence of Re on the diffusion of Al in the γ-phase of Ni-Al-Re system was insignificant. Materials Transactions Vol. 47 No. 5 2006 p: 1408-1411
