Abstract

The interdiffusion behavior of the Ni₃Al-Mo ternary system at 1423, 1473 and 1523 K was studied using Ni₃Al/Ni₃Al-Mo single-phase diffusion couples. The concentration-dependent interdiffusion coefficients were calculated over the whole diffusion range, and the average ternary interdiffusion coefficients were carefully determined in the middle of the diffusion zone. These ternary coefficients were also examined to estimate tracer diffusion coefficients of Mo in the Ni₃Al phase. The results were also used to explain the diffusion behavior of Mo in the Ni ₃Al-based superalloy IC-6.
