Description
The joining of hot rolled aerospace quality AZ31B-H24 magnesium alloy (Mg, 2.5-3.5%Al, 0.7-1.3%Zn, 0.2-1.0%Mn) sheets (thickness 4.95 mm) was investigated using an MTS ISTIR friction stir welding (FSW) machine, the quality of the butt joints produced was characterised, and the operating range for forge force was established. FSW was performed perpendicular to the workpiece roll direction at 1750 rpm clockwise tool rotational speed and 8 mm/s welding speed, controlled through both load (7.25-8.5 kN forge force) and pin depth (4.7 mm from pin bottom to workpiece top surface). Results obtained with respect to surface morphologies, areas of weld nugget, thermomechanically affected zone and HAZ at both advancing and retreating sides, grain size and Vickers microindentation hardness are presented.
