tungsten inert gas welding brazing of az31b magnesium alloy to tc4 titanium alloy
Journal of Materials Science & Technology, 2016Co-Authors: Guangmin Sheng, Hui Wang, Ke Feng, Xinjian YuanAbstract:Tungsten inert gas (TIG) welding–brazing technology using Mg-based filler was developed to join AZ31B Mg alloy to TC4 Ti alloy in a lap configuration. The results indicate that robust joints can be obtained with welding current in the range of 60–70 A. The joint interface was found to be likely composed of Mg–Ti diffusion reaction layer accompanied with Mg17Al12 precipitate phase, indicating that metallurgical joining was achieved. The optimized joint with average tensile-shear strength of 190 N/mm2 was obtained and fracture occurred at the Ti/fusion zone interfacial layer during tensile test. Moreover, the fracture surface was characterized by equiaxed dimple patterns accompanied with a few Lamellar Tearing. Finally, finite element modeling (FEM) numerical simulation was developed to analyze the distribution characteristics of the temperature field of joints.

Microstructure and mechanical properties of tungsten inert gas welded-brazed Mg/Ti lap joints
Science and Technology of Welding and Joining, 2014Co-Authors: Guangmin Sheng, Xinjian Yuan, Yongqiang Deng, Kunlun TangAbstract:The tungsten inert gas (TIG) welding–brazing technology using Mg based filler was developed to join AZ31B Mg alloy to TA2 pure Ti in a lap configuration. The results indicate that robust joints can be obtained with welding current in the range of 60–70 A and welding speed of 0·2 m min−1. The joints were found to be composed of the coarse grained fusion zone accompanied with the precipitated phase of Mg17Al12, and a distributed Mg–Ti solid solution zone at the interface of Mg/Ti, indicating that metallurgical bonding was achieved. The maximum tensile–shear strength of 193·5 N mm−1, representing 82·3% joint efficiency relative to the Mg alloy base metal, was attained. The optimised Mg/Ti joint fractured at Mg fusion zone upon tensile–shear loading, mainly caused by grain coarsening. Moreover, the fracture surface practically consisted of scraggly areas, which was characterised by equiaxed dimple patterns accompanied with a few Lamellar Tearing.
