| 摘 要： | 在Gleeble-1500热模拟试验机上, 通过高温压缩实验对316L不锈钢的动态再结晶行为进行了系统研究. 结果表明:316L不锈钢热变形加工硬化倾向性较大, 在真应力应变曲线上没有出现明显的应力峰值σ_p;316L不锈钢在热变形过程中发生了动态再结晶, 但只是在局部区域观察到了动态再结晶晶粒. 对动态再结晶的实验数据进行拟合, 得到316L不锈钢的热激活能和热变形方程, 并给出了发生动态再结晶的临界应变和临界应力以及Zener-Hollomon参数和稳态应力的关系.

| Abstract: | Dynamic recrystallization(DRX)in 316 L stainless steel was systematically studied by high temperature compression tests on a Gleeble-1500 thermal simulation testing machine.The results show that 316 L stainless steel has a large hot work-hardening tendency and there is no peak stress on its true stress-strain flow curves.DRX occurs in the hot working of 316 L stainless steel,but DRX grains can be observed only in the local area of metallographic phase.The activation energy for deformation and the thermal de... |
