Investigation of the process of diffusion bonding of alloys based on titanium nickelide

Abstract

The results of investigations of diffusion bonding of an alloy based on titanium nickelide are presented. The effect of the welding conditions on the strength of the joint in sheet semi-finished products is investigated. The experimental results show that the main reason for the reduction in the mechanical properties of the welded joint is the interaction of the weld surfaces with residual oxygen. This results in the formation of brittle intermetallic compounds enriched with titanium at the periphery of the weld zone.
