摘要(Abstract)：

为研究超纯铁素体不锈钢的再结晶退火对板材抗皱性的影响,采用拉伸试样表面粗糙度测量、X射线衍射(XRD)和电子背散射衍射(EBSD)技术对再结晶程度不同的板材表层和中心层的起皱程度、显微组织和织构进行了检测分析。结果表明,再结晶程度不同的板材具有不同的表面抗皱性;晶粒细小,尺寸均匀度好的再结晶退火组织有利于提高板材的表面抗皱性;退火钢板中心层再结晶程度较表层深,且起皱严重。分析认为:超纯铁素体不锈钢板材中心层再结晶形成的强点突出的γ纤维织构以及大范围的γ纤维取向团簇是造成板材表面起皱的重要原因;表层由于再结晶程度较弱,形成的γ纤维织构在γ取向线上分布均匀、无明显织构强点,显微组织也较为精细,因此对板材的起皱形貌具有缓解和覆盖的作用。
