通过穆斯堡尔谱、透射电镜、x射线和磁测量等手段研究了将普通FeCrCo合金中Cr,Co元素含量提高、并加入Mo,Zr元素后合金矫顽力的变化,发现其值76kAm比普通值40—52kAm高50%以上.对该合金不同热处理阶段的穆斯堡尔谱的测试表明,合金的微观结构与普通FeCrCo合金有显著的不同.固溶处理后合金单相性好,不产生对磁性起破坏作用的γ相;磁场热处理过程中,发生原子的重新排布,α2相开始出现,两相结构基本确定;分级回火后,调幅分解进行得更彻底,合金内部完全形成调幅结构,与低矫顽力合金相比,铁磁性的α1相更容易形成.
The changes of coercivity of Cr and Co elements in common FeCrCo alloy after adding Mo and Zr elements were investigated by means of Mossbauer spectroscopy, transmission electron microscopy, X-ray and magnetic measurements. The results show that the value of 76kAm The ordinary value of 40-52kAm more than 50% .Musbauer spectrum of the alloy at different stages of heat treatment tests showed that the alloy microstructure and ordinary FeCrCo alloy significantly different after solution treatment, alloy single phase is good, not The magnetic phase heat treatment process, atomic rearrangement occurs, α2 phase began to appear, the two-phase structure is basically determined; after grading and tempering, AM decomposition carried out more thoroughly, the complete formation of the interior of the alloy amplitude modulation Structure, the ferrimagnetic α1 phase is easier to form than the low-coercivity alloy.
