Presentation Title B15: Effect of Temperature and Strain Rate on Mechanical Response of ZEK100 Mg Alloy Sheet

Abstract Scope The effect of temperature (25°C-200°C) and strain rate (10<SUP>-3</SUP>-10<SUP>3</SUP> s<SUP>-1</SUP>) on the mechanical response of rare-earth alloyed ZEK100 sheet along the RD and TD is characterized. ZEK100 sheet exhibits strongly anisotropic sensitivity of flow stress on temperature and strain rate. At lower temperatures, the RD yield strength is strain rate- and temperature-sensitive, while the hardening rate shows only mild sensitivity to strain rate and temperature. The TD behavior is the opposite with strong rate- and temperature-sensitivity of hardening rate, but low sensitivity in the yield strength. With increasing temperature, both directions recover a more conventional thermal softening response. The cause of this orientation dependent temperature- and rate-sensitivity of ZEK100 sheet can be attributed to the initial crystallographic texture and the active deformation mechanisms. Constitutive modelling efforts to capture this complex response will be presented.
