PROTON-IRRADIATED RADIATION DAMAGE ABILITY PECULIARITIES OF THE STAINLESS STEEL AND REFRACTORY METALS

Abstract

In this work we have performed a systematical investigation of energy dependence of the radiation defects distribution profile in three different materials – tantalum, molybdenum and stainless steel of type 10Х18Н10Т–VD irradiated by high energy protons. It has been shown that in the stainless steel and tantalum, regardless of proton energy, the vacancy complexes similar by configuration appear which are described by the slightly expressed elastic channel.. At the same time the molybdenum radiation damageability consists of two components in each of which exists its own mechanism of defects formation.

Keywords: positrons, annihilation, tantalum, molybdenum, steel, protons, point de- fects, vacancy complex.
