Abstract

Explosive welding was used to form reliable joining between commercially pure titanium and stainless steel. To prevent cracking at the interface induced by brittle intermetallic bronze - tantalum interlayer was used. Microstructural characterization of produced composite was analyzed using optical and scanning electron microscopy as well as energy dispersive analysis. Determination of structure has revealed no micro defects such as cracks in the composite. Intermediate layer of 5 μm thick at the bronze - tantalum interface was formed. Structure of intermediate layer corresponds to highly dispersed mixture of tantalum and copper alloy particles. Ultimate strength of 4 layered composite is 1000 MPa that exceeds of ultimate strength of composite produced without interlayer. Analysis of fractograph indicates a high adhesion level between interactive materials.
