Abstract

The interdiffusion coefficient in Ni(Mo) solid solution, impurity diffusion of Mo in Ni, average interdiffusion coefficient of the NiMo-σ phase and activation energies for diffusion in solid solution and in the σ phase of the Ni-Mo binary system are evaluated through the diffusion couple approach. These results are utilized to identify the possible diffusion mechanism. Low activation energy in the σ phase indicates a grain-boundary-controlled diffusion process.
