摘要
采用Gleeble-3800热模拟试验机对60Si2Mn弹簧钢进行热压缩实验,研究了试样在变形温度为900～1000℃、应变速率为0.5～10s-1条件下的动态再结晶行为。结果表明,在900～1000℃变形,不同变形速率条件下试样均发生了明显的动态再结晶,变形温度对再结晶的影响大于应变速率。本实验条件下60Si2Mn弹簧钢形变激活能为85.15kJ/mol。
The dynamic recrystallization behaviors of 60Si2Mn spring steel were investigated by GleebIe-3800 hot simulator while the deformation temperature were 900-1000℃ and the strain rate were 0.5-10s -1. The results showed that dynamic recrystallization was occurred in 900- 1000℃. The effects of deformation tern perature on recrystallization are more obviously. In this experiment, the deformation activation energy of 60SiMn is 85.15kJ/mol.
