Heat transfer in surface layer of T15K6 heterogeneous hard alloy as a result of pulsed high-energy irradiation
A one-dimensional model of a hard alloy is proposed, which takes into account the heterogeneity of the physical properties of composite material by representing it as a sequence of 2 μm TiC and WC carbide particles. The influence of the energy density of pulsed high-current electron beams on depth of the melted layer and its microstructure is investigated. A comparison of the penetration depths of the hard alloy obtained by calculation and experimentally showed their good agreement. It was found that with increasing beam energy density due to melting of the carbides of the alloy the formation of a (Ti, W) C supersaturated tungsten solid solution and the transformation of WC®W2C during crystallization occur.
