On the Question of Primary Mass Transfer at the Boundary of Explosively Welded Titanium Alloy+nichrome Compositions

The results of studies of preferential mass transfer at the boundary of explosion-welded compositions X20N80+VT1-0, X20N80+OT4 and X20N80+VT20 are presented. It has been established that the structure of the interphase boundary is practically independent of the time parameters of the stabilizing heat treatment and is determined by its temperature. The main influence on the phase and chemical composition of the diffusion interaction zone formed during heating at the Ti-NiCr boundary is the degree of alloying of the titanium alloy. In this case, the diffusion gradient is predominantly directed towards titanium VT1-0 and its alloys OT4 and VT20.
