Abstract:
The hot compression experiments were carried out on Gleeble-1500D thermal simulator system and the hot deformation performance of non-quenched and tempered steel 49MnVS3 between 950°C∼1200°C with strain rate of 0.1~10 sec-1 were investigated by processing maps of dynamic material model. The deformation zone where dynamic recovery and dynamic recrystallization occurred is obtained according to true stress-strain curve. The variation law of strain rate sensitive factor m and power dissipation η is analyzed. Based on the analysis on m,η and instability criterion , the instability zone with strain of 0.3 and 0.5 is analyzed by contrastive analysis method. It is found that the hot processing safety zone of this metal accords to each other. Taking the deformation parameters when dynamic recrystallization happened in hot processing safety zone as deformation conditions, the optimal processing safety zones of this alloy are determined to be 2~10 sec-1 for strain rate and 1150~1200°C for processing temperature.
