摘要
以填加大剂量La制备铁镧合金,分析比较了纯铁和Fe-La合金锻造状态、正火状态下的组织,对Fe-La合金夹杂物进行了能谱分析.结果表明,大剂量La有很明显的变质钢液和细化晶粒的作用.纯铁在正火时发生了块状相变,Fe-La合金则没发生块状相变.
The microstructures of Fe-La alloys were investigated. The experimental results show that the addition of large amount of La has significant modification effect on the microstructures of pure iron.
