利用机械硬度和居里温度的测量，建立了Fe-Cr-Co永磁合金中α相的可磁化带。结果表明，Fe-Cr二元系的分解间隙发展为Fe-Cr-Co三元系，钴的加入提高了分解温度，扩大了富铁相（α1）和富铬相（α2）的浓度差。例如，Fe-31%Cr-23%Co合金的α相在低于670°C时表现出可熔性间隙，并且在600°C下分解成65%Fe-32%Co-3%Cr的（α1）相和69%Cr-21%Fe-10%Co的（α2）相。
The miscibility gap of the α phase in Fe-Cr-Co permanent magnet alloys is constructed using mechanical hardness and Curie temperature measurements. It is found that the miscibility gap of the Fe-Cr binary system develops into Fe-Cr-Co ternary system, and that the addition of cobalt raises the decomposition temperature, and extends the difference in concentrations between the iron rich phase (α1) and the chromium rich phase (α2). For instance, the α phase of an Fe-31%Cr-23%Co alloy exhibits a miscibility gap below 670°C, and decomposes into the (α1) phase of 65%Fe-32%Co-3%Cr and the (α2) phase of 69%Cr-21%Fe-10%Co at 600°C.
