Abstract Austenitic stainless steel 316L was investigated by a combination of in-situ biaxial straining and subsequently by in-situ annealing within a Carl Zeiss Sigma FEG-SEM. A Micromecha Proxima stage was used to impart biaxial strain on the sample, results were compared with macro scale testing to validate the method, and physical properties were established in close correlation to macro scale tests. Samples were subsequently subjected to annealing cycles using a Gatan Murano 525 heated stage to assess the influence of imparted strain on the recrystallization kinetics of the material. Following annealing trials the material was observed to initiate recrystallization around 100 °C earlier within heavily strained samples at 750 °C in comparison to 850 °C within unstrained samples.

316L奥氏体不锈钢在原位双轴变形和退火过程中的显微组织演变

摘要 奥氏体不锈钢 316L 通过原位双轴应变和随后在 Carl Zeiss Sigma FEG-SEM 内原位退火的组合进行研究。Micromecha Proxima 平台用于对样品施加双轴应变，将结果与宏观测试进行比较以验证该方法，并建立与宏观测试密切相关的物理特性。随后使用 Gatan Murano 525 加热台对样品进行退火循环，以评估施加的应变对材料再结晶动力学的影响。在退火试验之后，观察到材料在 750°C 的重应变样品中更早地在 100°C 左右开始再结晶，而在未应变的样品中则为 850°C。
