A recent comment on a previously published paper had addressed an invalid explanation of the off-diagonal interdiffusion coefficients of the β-Ni(Al,Cr) phase in the Ni–Cr–Al system according to the symmetrical property of the thermodynamic matrix. In this paper, the experimental data presented by Hou et al. were re-analyzed and the interdiffusion coefficient matrix was estimated again. The results of the analysis were discussed in terms of a brief reply to the comments of Liu and Liang.
