摘要(Abstract)：

通过对3种不同成分的无取向硅钢退火板进行微观组织观察以及分别使用XRD和EBSD进行宏观织构和微观织构观察,研究了3种典型元素对无取向硅钢组织和再结晶织构的影响。结果表明:无取向硅钢再结晶组织对其磁性能有影响,晶粒尺寸越大,无取向硅钢的磁性能越好,1.35Si-0.25Mn-0.28Al的再结晶平均晶粒尺寸达51.6μm,铁损值达3.577 W/kg。Si和Al元素有利于平均晶粒尺寸的增大,Mn含量的提高有利于减少夹杂物对晶粒长大的限制。无取向硅钢再结晶织构主要由强的γ织构(特别是{111}<112>织构)和弱的立方织构以及高斯织构等组成。有利织构中,立方{100}<001>织构和旋转{100}<011>立方织构含量较高,1.35Si-0.25Mn-0.28Al钢中立方织构含量达8.2%,1.33Si-0.17Mn钢中旋转立方含量达7.8%,有利织构含量越高,磁感应强度值越大,1.35Si-0.25Mn-0.28Al钢的磁感应强度达1.739 T。铜型{112}<111>织构和黄铜{110}<112>织构组分含量较低,1.33Si-0.17Mn钢在退火样品中黄铜织构最多,其比例仅为1.4%。无取向硅钢的化学成分对织构组成有影响,Al和Si含量的增加有利于{111}<121>织构和立方织构组分的增加、不利于{111}<110>组分和高斯织构增加,在1.35Si-0.25Mn-0.28Al钢中{111}<121>织构的含量达44.3%而{111}<110>织构含量为17.2%,高斯织构含量仅为1.2%。Mn的含量一定程度上有利于增加无取向硅钢中旋转立方织构的含量。
