Abstract

The shear strength (τ) of overlap shear test pieces made by solid state diffusion bonding or by machining thin (2.5 or 4 mm thick) Al-Li 8090 alloy sheet has been determined for various overlap lengths (/). When / < 3 mm, τ was independent of / and equal to 188 to 202 MPa for the bonded joint and 199 to 209 MPa for the base metal sheet. The lower mean shear strength of the bonded joint was caused by the lower resistance of intergranular fracture in the planar grain boundary at the bond interface. The bond strengths were, however, greater than those previously reported for joints in 8090 alloy made by solid-state or liquid-phase diffusion bonding and about a factor of 7 greater than those for adhesive bonded joints.
