Abstract

In this study, deformation behavior of AM30 magnesium alloy is investigated in the hot working regime and empirical relations are developed. Compression tests were performed in the 0.001-10s(-1) strain rate range and 423-623K temperature range to obtain the mechanical properties. The compression curves were fitted using two approaches, viz. piecewise linear fitting and a Johnson-Cook type relation. Piecewise linear fit is found to be appropriate for describing the mechanical behavior in the dynamic recrystallization (DRX) regime as compared to the proposed Johnson-Cook type relation. The Johnson-Cook type model is not able to capture the essential feature of DRX, particularly at high strain rates.
