摘要
对316LN不锈钢进行高温等温压缩试验,热压缩应变速率为0.003 s-1、热变形温度为800~1 050℃。结果表明,热变形期间主要发生了加工硬化、动态回复与再结晶的竞争作用,材料具有明显的软化趋势。并且,随着温度的升高,动态再结晶形核长大速率加快。
The high-temperature isothermal compression experiment was carried out on stainless steel 316LN. The strain rate during the compression is 0.003 s^-1, and the thermal deformation temperature is from 800 ℃ to 1 100 ℃. The results show that during the thermal deformation, the process hardening, dynamic recovery and recrystallization play a major role, and the materials have a tendency of softening. Furthermore, the growth rate of dynamic recrystallization nucleation increases with the increase of temperature.
