Abstract

The influence of energy density and pulse count under the effect by compression plasma flows (CPFs) and high-current electron beams (HCEBs) on the melting depth and microstructure of modified layers of T15K6 alloy is investigated. A method of computer modeling of heat transfer under such high-power effects on the hard alloy taking into account the bulk ratio of alloy components, variations in their thermal characteristics with an increase in temperature, difference in the pulse shape, and corresponding spatial energy release is proposed. The comparison of calculated melting depths of alloy components for HCEBs and CPFs with the experimental data in a range of energy densities of 30–50 J/cm2 showed their good agreement. The interrelation of the features of the thermal effect of HCEBs and CPFs with the melting depth and microstructure of modified layers of T15K6 alloy is revealed.
