The abnormal flow behavior of Mg-9Gd-4Y-2Zn-0.5Zr alloy during hot tensile deformation at high temperature and low strain rate

The abnormal flow behavior of Mg-9Gd-4Y-2Zn-0.5Zr alloy during hot tensile deformation at high temperature and low strain rate

Through hot tensile testing, the flow stress-strain curves of Mg-9Gd-4Y–2Zn-0.5Zr alloy after repetitive upsetting-extrusion (RUE) have been obtained. Under high-temperature and low-strain-rate conditions (450°C-0.0001s⁻1, 500°C-0.001s⁻1, and 500°C-0.0001s⁻1), the alloy exhibits excellent plasticity...
