Microstructure and mechanical properties of hot extruded Mg-8.89Li-0.96Zn alloy

The numerical simulation and experiments were conducted to study the hot extrusion of Mg-8.89Li-0.96Zn alloy. The extrusion process was modelled based on finite element method, and the effects of extrusion speed on the distribution of flowing velocity, effective strain rate, and temperature were clarified. Moreover, the extrusion experiments were carried out at varied extrusion speeds, and both the microstructure and mechanical properties of the...
