Abstract

Compressive deformation behavior of Mg-5Sn-2.5Pb magnesium alloy was investigated at the temperature range from 250 to 450°C, strain rate range from 0.001 to 10s-1 and the maximum deformation degree of 60% on Gleeble-3500 thermal simulator. The constitutive equations were established by taking peak stresses as the function of temperatures and strain rates. The results show that the flow stress significantly affected by deformation temperature and strain rate, and the flow stress decreases with the increase of deformation temperature and the decrease of strain rate. The deformation activation energy and stress exponent were evaluated by the hyperbolic-sine mathematics model and the hot deformation constitutive equation was established.
