Abstract
The results of studying the variation in the microhardness of SAV-1 and AMG-2 aluminum alloys after irradiation with neutrons with a fluence of 1016 to 1020 cm−2 are presented. Two ranges of variation in the microhardness dependent on the indenter load are revealed, which are retained in the entire fluence range. A strong dependence of the H μ value on P for loads less than 50 g (in the first range) is most likely caused by the physicochemical state of the surface layer.
