Abstract

A quantitative measure of the effect of processing variables on the shear strength of solid state diffusion bonds is often difficult to obtain because of the scatter in test data. This may be reduced by improving the bonding and testing techniques. Two jigs for bonding and testing small Al-alloy lap shear test pieces are described. These jigs enabled the precise measurement of shear stress-strain curves for lap joints and led to reproducible shear strength values. Results obtained for diffusion bonded lap joints between clad Al-Zn-Mg (7010) alloy are described.
