Kinetics of diffusion interaction in the Ti-NiCr system layered composites

The results of investigation the diffusion interaction kinetics at boundary explosion welded Ti-NiCr system compositions during heat treatment are presented. structure, chemical and phase composition formed zones also studied. It is shown that layered zone a temperature below eutectoid transformation. Diffusion consists solid solutions based on Ti2Ni, TiNi, TiNi3 intermetallic compounds, as well chromium-based solution inclusions along with NiCr alloy. An increase in above transformation leads to an intensification growth nickel into titanium alloy formation structure it. use alloyed alloys instead commercially pure does not affect zones, but slows down processes.
