On the Issue of Radiation-Induced Instability in Binary Solid Solutions

Abstract EN

The stability of a binary solid solution under irradiation has been studied.

This has been done by performing linear stability analysis of a set of nonlinear reaction-diffusion equations under uniform irradiation.

Owing to the complexity of the resulting system of eigenvalue equations, a numerical solution has been attempted to calculate the dispersion relations.

The set of reaction-diffusion equations represent the coupled dynamics of vacancies, dumbbell-type interstitials, and lattice atoms.

For a miscible system (Cu-Au) under uniform irradiation, the initiation and growth of the instability have been studied as a function of various control parameters.
