Structural analysis of three-metal explosion joint: zirconium-titanium-steel

Abstract

The influence of applied explosion joining parameters on the structure and strength of three-metal joints: Zr-Ti-Steel is analyzed in this paper. Zirconium was explosively clad on steel over an inter-layer of titanium. Zirconium-titanium-steel joint is produced during simultaneous cladding operation using a single cladding shot and plan parallel joining scheme. The metallographic analysis of interfaces Zr/Ti and Ti/Steel structures and microhardness measuring are performed. Mechanical testing of bond strength is performed on both interfaces by shear strength examinations.
