Влияние дефектной структуры и режимов химико-термической обработки на концентрацию кислорода в сплаве системы V-Cr-Zr-Ta

Abstract

This work presents investigation of influence of the defect structure and chemical-heat treatment duration on oxygen concentration in the vanadium based alloy. It was found that with the increasing of plastic deformation degree oxygen concentration increases due to grain refining and dislocation density increasing. Mechanical properties investigations show that the increasing of oxygen concentration leads to significant microhardness increasing.
