Separation of a Solid Solution of a Fe-Ni Invar Alloy with Different Types of Point Defect Sinks under Electron Irradiation

摘要

Solid solution separation is studied for electron irradiation of a Fe-Ni alloy with different types of sinks of point defects in the form of dislocations and deformation-induced vacancy clusters. It is shown that the efficiency of deformation-induced dislocation sinks exceeds that of deformation-induced vacancy clusters. In isochronous annealing, two sub-stages of dissociation of vacancy clusters with dissociation energies of 1.2 and 1.5 eV are observed, which are independent of the method of creating vacancy clusters – deformation or electron irradiation.
