【摘要】：采用X射线衍射技术和光学显微分析等方法,研究了同步和异步冷轧方式对SUS430铁素体不锈钢微观组织、织构演变以及力学和成形性能的影响。结果表明,与同步冷轧相比,由于异步轧制剪切变形的引入,可使异步冷轧板材的平均晶粒尺寸减小。在同步冷轧过程中,其二次冷轧再结晶织构为完整的γ纤维织构,导致铁素体不锈钢的最终性能优于同步一次冷轧;而在异步冷轧过程中,异步一次冷轧再结晶织构为强点{111}1ˉ1ˉ2的γ纤维织构,异步二次冷轧再结晶织构属于随机取向织构,其结果是异步一次冷轧板材的性能优于异步二次冷轧。综合分析表明,与异步二次冷轧方式相比,同步二次冷轧方式有利于铁素体不锈钢性能的提高。
[Abstract]:The effects of synchronous and asynchronous cold rolling on the microstructure, texture evolution, mechanics and formability of SUS430 Ferric stainless steel were studied by means of X-ray diffraction and optical microscopic analysis. The results show that compared with synchronous cold rolling, the average grain size of asynchronous cold rolled sheet can be reduced due to the introduction of shear deformation in asynchronous rolling. In the process of synchronous cold rolling, the re-crystallization texture of secondary cold rolling is a complete gamma fiber texture, which leads to the final properties of Ferrified stainless steel are better than those of synchronous primary cold rolling. In the process of asynchronous cold rolling, the recrystallized texture of asynchronous primary cold rolling is a gamma fiber texture with strong point {111} 1 鈮，
