Description
Summary:The microstructure evolution, texture and tensile properties of the Mg-8Li dual-phase alloys processed by hot-extrusion and friction stir processing were investigated. It was found that the friction stir processing was more advantageous when compared with hot-extrusion in achieving the superior mechanical properties. The tensile strength, yield strength and elongation of the as-FSPed alloy reached 235.4 MPa, 185.3 MPa and 35.6%, respectively. The outstanding strength-ductility combination of the ­as-FSPed Mg-8Li alloy was ascribed to refined grains, weakened texture and formation of high-fraction high angle grain boundaries.
