Abstract

The hot compression deformation behavior and microstructure of as-cast Mg–5.0Sn–1.5Y–0.1Zr alloy were investigated by performing isothermal hot compression tests. The tests were conducted using a thermal mechanical simulator at 250–450 °C and strain rates ranging from 0.002 to 2 s−1, with a maximum deformation strain of 50 %. The effects of the deformation parameters on the microstructure evolution of the Mg–5.0Sn–1.5Y–0.1Zr alloy were discussed. The study revealed the flow behavior and the deformation mechanism of the Mg–5.0Sn–1.5Y–0.1Zr alloy. The dependence of flow stress on temperature and strain rate was described by a hyperbolic sine constitutive equation. Through regression analysis, the activation energy of 223.26 kJ mol−1 for plastic deformation was determined by considering flow stress at a strain rate of 0.2. Microstructure observation showed that dynamic recrystallization occurred extensively along grain boundaries at temperatures higher than 300 °C and strain rates lower than 0.02 s−1. This observation provides a theoretical basis for the manufacture and application of the Mg–5.0Sn–1.5Y–0.1Zr alloy.
