Diffusion Bonding between AZ91 Magnesium Alloy and 7075 Aluminum Alloy

Abstract:

Article Preview

In the present investigation, AZ91 magnesium alloy was vacuum diffusion bonded to a 7075 aluminum alloy. The effects of the welding temperature and holding time on the joint shear strength are investigated with the help of electron microscopy, micro-hardness and electronic universal testing machine. It is shown that in certain extent, the welding temperature and holding time have great effect on the joint shear strength. The maximum of joint shear strength is obtained and the width of diffusion layer is 34.36μm with the bonding temperature being 470°C and the holding time reaching 60min.
