Achieving superior mechanical properties in a low-alloyed magnesium alloy via low-temperature extrusion

A low-alloyed Mg-1.2Zn-0.1Ca (wt.%) alloy was extruded at low temperatures. The alloy extruded at 150 °C exhibits a yield strength (YS) of 374 MPa and an elongation of 14.2%. The YS is superior to most Mg–Zn–Ca alloys, and can compete with high-alloyed AZ91 and Mg-RE alloys.
