Structural-Phase States and Mechanical Properties of VK8 Alloy after Gamma-Quanta Irradiation

Abstract:

. This article on the basis of experimental studies shows the data about γ-quanta affecting VK8 alloy. With structural studies it is found that γ-quanta irradiation leads to the volume fraction of the ternary phase and a decrease in the concentration of defects in cobalt. The irradiation γ-quanta irradiation leads to an increase in the content of the ternary compound type η-phase (Co_xW_yC) of variable composition and decrease the concentration of defects in the cobalt matrix. Formation of the ternary compound by irradiation determines the mechanical properties of the alloy, because the appearance η-phase results in an alloy with a grain size of less hardness alloys.
