Abstract
The hot deformation behavior of the novel Pb-Mg-10Al-1B alloy has been investigated by hot compressive tests in the temperature range from 453 to 613 K within the strain rate range of 0.01-1 s−1 using a Gleeble-1500 thermal simulator testing machine. The results show that the flow stress increases with increasing strain rate and decreasing temperature. The hot deformation behavior can be described by a constitutive equation with hyperbolic sine function or Zener-Hollomon parameter. The hot deformation activation energy of Pb-Mg-10Al-1B alloy is 151.2543 kJ/mol. The processing map at the strain of 0.4 exhibits an instable deformation domain of 460-520 K at 0.06-1 s−1. According to the processing map, the optimum hot-working conditions for Pb-Mg-Al-B alloy are 573 K and 0.01 s−1.
