Microstructure and Mechanical Property along 3D Directions of AZ31 Magnesium Joint Welded by FSW

Abstract:

As-cast AZ31 magnesium alloys was fabricated with travel speed of 50 mm/min and rotating rate of 1500 r/min by means of friction stir welding (FSW). The microstructure and mechanical property of the joint along three dimensions (3D) directions were investigated by optical microscopy (OM) and tensile experiment. The results show that the FSW joint is characterized with asymmetric gradient in 3D. The mechanical properties of the slice decrease from the top to the bottom of joint and starting part is the weakest unit, while middle part corresponds to the strongest one.
