Abstract

Two martensitic steels (Fe-8.5 Cr-0.9 MoVNb and Fe-9.0 Cr-1.8 MoVNb), one ferritic steel (Fe-17 Cr-1.5 MoVNb), 316 stainless steel and Ni3Fe were irradiated with 2 MeV electrons to 1× 1023 e/m2. The damage recovery was studied by positron annihilation and differential scanning calorimetry (DSC). Results suggest that vacancies migrate and disappear below 330 K in the martensitic phase. Vacancies in the ferritic and austenitic phases disappear around 420 K, enhancing the precipitation. Ordered Ni3Fe has three DSC annealing stages between 400 and 600 K. © 1985.
