Achieving high-strength in Mg-0.8Zn-0.2Zr (wt.%) alloy extruded at low temperature

High strength low-alloyed Mg-0.8Zn-0.2Zr (wt.%) alloy was fabricated by conventional extrusion at low temperature. The alloy exhibited a tensile yield strength of 330 MPa and an elongation to failure of 15.5%, which is superior to the vast majority of extruded ZK60 and AZ80/AZ91 commercial alloy containing heavy alloying.
