摘要
文中研究了磁场热处理参数对低钴型Fe-Cr-Co系永磁合金的显微组织及磁性能的影响,探讨了生产上经常发生磁性能不稳定的原因及改进措施。结果表明,精确控制磁场热处理温度是优化调幅分解组织,使低钴型Fe-Cr-Co系合金稳定达到最佳磁性能的关键。较高的磁场强度也是实现热处理优化的重要条件之一。在生产条件下,通过优化热处理工艺收到改善与稳定低钴型Fe-Cr-Co系合金磁性能的良好效果。
In this paper, effects of parameters of magnetic field heat treatment on microstructure and magnetic properties are studied in an Fe-Cr-Co alloy with low cobalt content. Reasons of instability in magnetic properties which often occur in production and measure to be taken to solve this problem are discussed. The results show that it is impertinent to precisely control the temperature at which the magnetic field heat treatment is carried out. This will be beneficial to improve Spinodal decomposition structure and obtain optimum magnetic properties. Higher magnetic field intensity is also one of the conditions to optimize the heat treatment. Lnder condition of production, the magnetic properties of the Fe-Cr-Co alloy with low Cobalt content can be improved and stabilized through optimizing the heat treatment parameters.
