摘要
利用金相显微镜、X射线衍射技术及电子背散射衍射(EBSD)技术,研究了两种精轧温度对Nb稳定化的Cr17铁素体不锈钢薄板成形性及表面皱折的影响.结果表明:低精轧温度有利于消弱冷轧退火板的γ纤维再结晶织构的偏转,提高γ纤维再结晶织构在各层的强度,改善沿着板厚的织构均匀性,促使冷轧退火板形成更少的取向晶粒簇.因此,采用较低精轧温度提高了成品板成形性能,减轻了成品板表面皱折.
The influence of high/low finish-rolling temperature on the formability and ridging of Nb micro-alloyed 17%Cr ferritic stainless steel sheet was investigated by using metalloscope,XRD and EBSD（electron back-scattered diffraction）.Based on finish-rolling temperature of 930 ℃ and 810 ℃ comparison,the results showed that,for the cold-rolled and annealed sheets,the low finish-rolling temperature is beneficial to the alleviation of the deviation from exact 〈111〉 fiber axis,strengthening γ-fiber texture at different layers along sheet thickness,with textural homogeneity improved and a less frequent formation of orientation colonies in the finished sheets.Therefore,the finished sheets which were hot rolled at low finish-rolling temperature may enhance their formability with ridges reduced.
