Effect of Heat Treatment on Mutual Diffusion of U-Mo Alloy with Nb

Solid bonding diffusion couples of U-Mo/Nb have been made by Covering and Hot rolling. The diffusion couples were heat-treated at 760℃ and 790℃. The thickness of diffusion layers were measured by Energy Dispersive Spectrometer (EDS) and the relationships between annealing time and thickness of the diffusion layers were also studied by the Non-linear curve fitting. The results indicated that it has biggish difference between the simulation equations under the two temperatures.
