Composition dependence of radiation induced patterns in non miscible alloys
Abstract
We present a theoretical approach exhaustively predicting the variety of steady-state shapes emerging under irradiation in thermodynamically unstable binary mixtures. We show that stripes or honeycomb structures are controlled not only by the two classical irradiation parameters: the irradiation flux and the temperature, but also by the nominal composition of the mixture. A rationale is thereby established for the results found in the literature. Moreover, the present developments lead to a simple methodology for predicting irradiation patterning without solving any evolution equation. It is foreseen, that this hands-on method will allow preparing materials with desired properties stemming from metastable irradiation microstructures produced on demand.
