Abstract Friction stir processing (FSP) was used to modify the surface layer of AZ91 magnesium alloy. The treatment carried out using a jet cooling nozzle, generating stream cold air and enabling intensive friction processed (FSPed) zone. Single-pass FSP tool rotational speed 500 rpm travel 30 mm/min. conducted truncated cone-shaped with threaded side surface. Strong grain refinement microstruc...

Friction stir welding (FSW) is a solid-state process capable of joining wide range light metals. However, liquation and solidification may occur during dissimilar metals which leads to eutectic formation. This article aims discover the influence tool rotation speed on formation structure friction aluminum magnesium. To do so, was performed at 600 950 rpm join pure ECO-AZ91 magnesium alloy in la...

As the lightest engineering materials, magnesium alloys have been widely used. Because of specific chemical and physical characteristics, weldability alloy is poor. Adopting suitable welding technology improving quality welded joints key to their successful application. According previous research data, it was found that combined action magnetic field activated flux has a positive effect on imp...
