Abstract

Three types of commercial austenitic stainless steels, 1.4307 (AISI 304 L), 1.4404 (AISI 316 L) 1.4845 (AISI 310 S) with different chemical compositions, are subjected to severe plastic deformation at room temperature by a unique Dual Rolling Equal Channel Extrusion (DRECE) method. Its impact is evaluated from the viewpoint of microstructure analyses, X-ray diffraction, and macroscopic magnetic properties completed by microscopic Mössbauer characteristics. The study also includes the solution annealing at 950 °C for 0.5 h to follow the recovering austenitic structure and paramagnetic state of steels with the aim to offer more information with respect to new technical applications. The results show the importance of the steel's chemical composition and microstructure, mainly grain size, on the stability of the austenitic structure closely associated with the paramagnetic behaviour.

摘要

三种具有不同化学成分的商用奥氏体不锈钢，1.4307（AISI 304L）、1.4404（AISI 316L）、1.4845（AISI 310S），通过独特的双道次轧制等通道挤压（DRECE）方法在室温下进行严重塑性变形。从微观结构分析、X射线衍射以及通过微观穆斯堡尔特性完成的宏观磁性等角度对其影响进行评估。该研究还包括在950°C下进行0.5小时的固溶退火，以追踪钢的奥氏体结构恢复和顺磁状态，旨在提供更多关于新技术应用的信息。结果表明，钢的化学成分和微观结构，主要是晶粒尺寸，对与顺磁行为密切相关的奥氏体结构稳定性具有重要意义。
