Abstract

The study has established that reactor radiation leads to a significant increase of interdiffusion coefficients in a Mo-W alloy compared to thermally activated diffusion at temperatures of ~1500оС. Furthermore, a weakening of their concentration dependence is observed. The approximation procedure developed in this work allowed approximating experimental data for each sample using variation of only one parameter. It has been demonstrated that the interaction of molybdenum and tungsten nuclei with fast neutrons as well as with hard gamma quanta may cause the observed diffusion effects.
