SEPARATION OF A SOLID SOLUTION OF A Fe-Ni INVAR ALLOY WITH DIFFERENT TYPES OF POINT DEFECT SINKS UNDER ELECTRON IRRADIATION

DOI: 10.17804/2410-9908.2018.6.157-164

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.

Acknowledgments: The work was performed within the state assignment on the subject of Spin, No. АААА-А18-118020290104-2.

Keywords: irradiation, electrons, Fe-Ni Invar, deformation, sinks of point defects, solid solution separation
