Phase equilibrium in a binary alloy under cascade producing irradiation; Ravnovesie faz v binarnom splave pri kaskadoobrazuyushchem obluchenii

Abstract

The combined effect of radiation-induced segregation and cascade disorder-dissolution on the growth and stability of second-phase precipitates in a random binary alloy is considered. Radiation-altered coherent and incoherent solubilities are derived. It is found that under irradiation the quasi-stationary distribution of alloying elements is stable to spatial fluctuations in the local composition. From the stability analysis the time of formation of the segregation profiles around sinks is estimated. The nature of a low temperature threshold of radiation-induced precipitation at sinks in alloys of Ni-Si type is investigated. A method is presented to construct the radiation-modified phase diagram as well as the temperature-dose rate diagram. The calculations of these diagrams (also called structural-phase) are carried out for Ni-Si and Ni-Al alloys. The model predictions are compared with the available experimental data. 35 refs.; 6 figs.; 1 table. (author).
