چکیده
Abstract Hot deformation tests of 5CrNiMoV steel were performed at temperatures 700 to 870 °C and strain rates 0.001 0.1 s −1 using the DIL 805D thermomechanical simulator. The critical volume fraction models Dynamic Recrystallization (DRX) constructed based on work hardening theory. results showed that DRX decreases with increasing temperature decreasing rate, which implies occurs easily higher lower rates. average grain size model was established predict changes during hot deformation. Based processing maps Material Model (DMM) microstructure observation, optimum working parameters for are a 800 °C–870 °C, rate 0.001–0.05 .

The aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (DRX). The material used is 316 stainless steel. In order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °C with strain rates of 0.01-1s-1. The result shows that at the tempera...
