Abstract：

Based on double thermodynamics simulation research of 09CuPTiRe steel, the critical strain of second pass was obtained by using ln θε curves. Effects of hot deformation temperature and strain rate on behavior of second pass were discussed. The results show that the hot deformation behavior of second pass after dynamic recrystallization of first pass is different from that one in single pass. The critical strain of second pass decreases with decreasing the deforming temperature and increasing the strain rate. These results agree well with FEM simulation results of second pass.
