To investigate the effect of different extrusion temperatures (350 and 200 °C) on the tensile properties of backward extruded Zn-6Al alloys at room temperature, the microstructure and mechanical properties were studied using scanning electron microscope (SEM), electron back-scattered diffraction (EBSD), and electronic universal testing machine. The results show that with the decrease of extrusion temperature from 350 °C to 200 °C, the elongation of backward extruded Zn-6Al alloys increases from 98% to 198% at the strain rate of 10^-3 s^-1 due to the fine grains, high Schmid factor and non-lamellar structure.
