Phase structure and magnetic properties of SmCo x-0.4 Ti0.4 ribbons

  • 摘要: SmCox-0.4Ti0.4(x=5.0, 5.5, 6.5, 7.0)合金经42 m/s速度甩带快速凝固制成薄带,在真空热处理炉中,进行750 ℃两小时热处理.对制得的甩带状态和热处理状态合金薄带分别测试其相结构和磁性能.结果表明:SmCox-0.4Ti0.4合金甩带状态样品相结构随Co含量的不同而变化,其中x=5.0,5.5和6.5的合金样品由2∶ 17和1∶ 5两相结构组成;x=7.0成分样品由1∶ 7单相结构组成.甩带状态样品的比饱和磁化强度和比剩余磁化强度基本上线性增加,内禀矫顽力在合金成分为x=5.0时出现最大值,为1.01 T.薄带样品热处理前后均具有纳米晶结构,表现出剩磁增强效应.样品矫顽力机制主要为形核型,反磁化形核场主要来源于SmCo硬磁相大的磁晶各向异性及其纳米晶结构.热处理后,除x=7.0样品外,其余样品矫顽力均有所下降.
