- Abstract
A technological process was developed for friction stir processing of surfaces of parts from magnesium and aluminum alloys for structure modification directed on formation of layer of fine-grain alloy structure (grain size 1.2-4.5 mm) that is 16-63 times less than the initial metal grain size (75.8 mm). It is determined that the maximum temperature of alloy heating in zone of contact interaction of a tool with FS-processed layers of the samples from researched alloys has reached 340-380 °C. Analysis of effect of kinetic parameters of the tool on change of microstructure of modified surface layers of the parts and welded joints was carried out.
