Abstract

Using a single pass hot-rolling process, we fabricate AZ31/Ti multilayers with the thickness reduction in the range of 25% to 55%. The hot-rolled AZ31/Ti multilayers are heat-treated at 400 °C for 6, 12, and 24 h, respectively, in an argon atmosphere. Both the microstructure and deformation behavior of the AZ31/Ti multilayers are characterized. The experimental results reveal good bonding of the AZ31/Ti multilayers between AZ31 and Ti layers. There is no formation of any intermetallic compounds in the as-rolled and heat-treated AZ31/Ti multilayers. The good bonding between the Ti and AZ31 layers is the result of diffusion bonding whose thickness increases with increasing the heat-treatment time and thickness reduction. The shear strength of the AZ31/Ti multilayers increases with increasing the thickness of the bonding layer.
