分别在空气和N2中高温烧结得到了不同掺杂浓度的Fe3O4:Zn粉末.X射线衍射(XRD)结果表明,空气中烧结使得样品过氧化,生成大量的α-Fe2O3相,而N2环境下烧结可以获得较纯的ZnxFe3-xO4相.Zn2+在反尖晶石结构中A位的替位掺杂,影响到B位Fe阳离子的价态分布,电子输运依然保持了电子变程跳跃的传导机制.磁性测量结果显示低浓度的Zn2+掺杂对Fe阳离子之间的超交换耦合作用产生影响,也使负的磁致电阻的数值有所改善

用扫描电镜和透射电镜研究了自蔓延离心法制备的不锈钢内衬(Cr,Ni分别为13%~14%和14~16%)复合钢管不锈钢层的结晶特点和组织结构.研究表明,不锈钢熔体主要以柱状晶形式结晶,柱状晶由奥氏体组成,柱状晶间有一薄层铁素体,铁素体区有AlNi金属间化合物析出相,在奥氏体和铁素体相界的铁素体区一侧有σ相析出
