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.

РАССЛОЕНИЕ ТВЕРДОГО РАСТВОРА ИНВАРНОГО СПЛАВА FE-NI С РАЗНЫМИ ТИПАМИ СТОКОВ ТОЧЕЧНЫХ ДЕФЕКТОВ ПРИ ЭЛЕКТРОННОМ ОБЛУЧЕНИИ

Исследовано расслоение твердого раствора при электронном облучении в Fe-Ni-сплаве с разными типами стоков для точечных дефектов в виде дислокаций и деформационных вакансионных кластеров. Показано, что эффективность деформационных дислокационных стоков больше, чем эффективность деформационных вакансионных кластеров. При изохронных отжигах наблюдается две подстадии диссоциации вакансионных кластеров с энергиями диссоциации 1,2 и 1,5 эВ, которые не зависят от способа создания вакансионных кластеров: деформацией или облучением электронами.
