Phase Composition of the Interaction Zone Formed in the Ti-Cu System Composite in the Presence of a Liquid Phase

Abstract

It was shown that heat treatment of Ti-Cu system composites at temperatures above the melting temperature of copper (copper-nickel alloy) leads to the formation of an interaction zone, the structure and phase composition of which is determined by the temperature and time of existence of the liquid melt solid solution in contact with the interlayer. Other things being equal, an increase in the exposure time leads to an increase in the volume of reacted titanium and the weight fraction of titanium-rich intermetallic compounds in its structure.
