Abstract

The diffusion bonding of Titanium-Zirconium-Molybdenum Alloy (TZM) and Zirconium alloy (Zr-4) using a Ti interlayer was investigated. A solid solution transition layer (∼180 μm) formed at the Zr-4/Ti interface, with Zr diffusing into Ti in a dendritic-like pattern. In contrast, the Ti/TZM interface exhibited a thinner (∼6 μm), protrusion-like bonding layer due to Ti penetration. The joints bonded at 1020 °C exhibited the highest average tensile strength of 394.3 MPa. Fracture initiates at the Ti/TZM interface and propagates into the Ti interlayer, with ductile fracture on the Ti side and cleavage brittle fracture on the TZM side.
