| Abstract: | Dynamic recrystallization(DRX) behaviors of a heat-resistant martensitic stainless steel 403Nb during hot deformation have been investigated by single-pass thermo-mechanical simulative experiment at temperatures of 900-1150C and strain rates of 0.01-1 s 1.The results show that the true stress-true strain curves of this alloy can be classified into two types,one is of dynamic recovery and the other is of dynamic recrystallization.The DRX in 403Nb alloy is easy to occur at strain rates lower than 0.5 s1 and d... |
