Microstructure And Mechanical Property

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.

Microstructure And Mechanical Property

A thixomoulded magnesium alloy containing thermally stable Al2Ca phase was friction stir processed, and its microstructure and mechanical property were investigated. In friction stir zone, the cast structure of the base metal is replaced by fine magnesium grains containing fine dispersoides of Al2Ca. Due to the refined grain size of 0.8-1 μm, hardness of friction stir zone is higher than that of base metal. Texture was developed at top and bottom surfaces, (0002) being parallel to the plate surface, whereas (0001) plane is randomly oriented in the center of friction stir zone.
