On the Effect of Reactor Irradiation on Mo and W Interdiffusion

详细

It is demonstrated that reactor irradiation accelerates interdiffusion in the Mo—W alloy compared to thermally activated diffusion at a temperature of ∼1500°C. In addition, the concentration dependence of interdiffusion becomes weaker. A procedure allowing one to approximate experimental data by varying a single parameter is developed. It is demonstrated that the interaction of molybdenum and tungsten nuclei with fast neutrons and hard gamma radiation may induce the observed effects.
