摘要: 对Fe-49Co-2V和Fe-49Co-2V-0.3Nb两种合金室温与高温时的磁性能和力学性能进行了测试。结果发现:与室温磁性能相比,两种合金在高温下的饱和磁化强度Bs与矫顽力Hc均降低;与室温力学性能相比,两种合金在500 ℃时的高温抗拉强度都有所增加,其中 Nb元素的添加使合金力学性能强化的效果十分明显。两种合金经500 ℃时效处理168 h后,Fe-49Co-2V-0.3Nb合金经过高温时效后依然能保证具有良好的力学性能,添加了Nb元素后有助于改善合金的高温时效稳定性。

Abstract: Magnetic properties and mechanical properties of Fe 49Co-2V and Fe 49Co-2 V_0.3Nb alloys were measured at room temperature and high tempernature,respectively.The results show that the saturation magnetization B。and coercivity H。of both alloys decrease compared with room tempera ture,and tensile strength at 500 C of two kinds of alys is improved comparing with room temperature.The strengthening effct of Nb addition on mechanical properties is obvious.It is found that Fe 49Co-2V 0.3Nb alloy still has good mechanical properties after ageing at 500 C for 168 h.The addition Nb is helpful for the stabilty of high tempenature aging.

Key words: FeCo based soft magnet alloy, Nb addition, high temperature mechanical properties, aging treatment
