用Ni 3Al/Ni 3Al-Mo单相扩散偶研究了Ni 3Al-Mo三元系在1423、1473和1523 K下的互扩散行为。在整个扩散范围内计算了浓度依赖性互扩散系数，并在扩散区中间仔细确定了平均三元互扩散系数。这些三元系数也进行了检查，以估计示踪剂扩散系数的Mo在Ni 3Al相。研究结果也解释了Mo在Ni 3Al基高温合金IC-6中的扩散行为。
The interdiffusion behavior of the Ni3Al–Mo ternary system at 1423, 1473 and 1523K 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 Ni3Al-based superalloy IC-6.
