摘要

在运行过程中,许多 3D 打印部件可能会受到外部应变和/或高温的影响。然而,热机械行为,如塑性变形和再结晶,尚未得到深入分析,而由于三维打印引入了复杂的微观结构,因此对其进行研究很有意义。在本研究中,我们对激光粉末床熔融技术制造的奥氏体不锈钢 316L 样品在塑性变形和再结晶过程中的微观结构演变和硬度变化进行了表征。重点研究了打印状态和塑性变形状态下的再结晶动力学。研究还讨论了这些结果与传统制造样品结果的比较。本研究表明,三维打印样品的不均匀性会显著影响再结晶行为。

Recrystallization kinetics in 3D printed 316L stainless steel
During operation, many 3D printed components are likely to be exposed to external strains and/or high temperatures. However, the thermomechanical behaviours, e.g. plastic deformation and recrystallization, have not been thoroughly analysed, and are interesting to study because of the complex microstructure introduced by 3D printing. In the present work, the microstructural evolution and change in hardness during plastic deformation and recrystallization have been characterized in austenitic stainless steel 316L samples manufactured by laser powder bed fusion. The focus is on the recrystallization kinetics in both the as-printed and the plastically deformed state. It is discussed how these results compare to results for conventionally manufactured samples. The present study suggests that the inhomogeneity of 3D printed samples significantly affects the recrystallization behaviour.
