Microstructure and mechanical properties evolution of 6061 aluminum alloy formed by forward thixoextrusion process

► The globular microstructure of thixoformed parts obtain at the higher temperatures. ► The microstructure of thixoformed parts consists of relatively equiaxed grains. ► Precipitation phases decrease in the grain boundaries with increasing temperature. ► SEM results show the fracture surface of thixoformed parts has a mixture mode.
