摘要(Abstract)：

通过电子背散射衍射(EBSD)、扫描电镜(SEM)、X射线衍射(XRD)、光学显微镜(OM)等分析了Mn元素含量对富铁8系铝合金铸轧板组织的影响。结果表明:随着Mn元素含量的升高,铸轧晶粒从边部到中心的晶粒长短轴比减小,晶粒尺寸呈现出增大的变化趋势,且越接近中心越接近等轴晶;合金中心的第二相体积分数呈现出随着Mn元素含量的增加逐渐升高的变化趋势,且会促进β-Fe富铁三元相逐渐向α-Fe富铁四元相的转变;Mn元素含量会对合金的织构含量产生一定的影响,且会促进随机取向织构逐渐向FCC晶体结构中典型的β取向线织构的转变。

关键词(KeyWords)： 富铁8系铝合金;Mn元素含量;晶粒;化合物;织构
