• Low -temperature extrusion
• Ultrafine grains
• Mechanical properties

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.
