摘要：
The 600°C section of the Fe–FeS–NiS–Ni phase diagram was studied by optical and electron microscopy techniques, x-ray diffraction, and electron probe x-ray microanalysis. The results agree with the most reliable data available in the literature. The solid-solution regions identified are those of (FezNi1 – z)3 ± δS2(high-temperature heazlewoodite structure), (FezNi1 – z)S1 + δ, (FezNi1 – z)9 + δS8(pentlandite structure), α-(Fe,Ni), and γ-(Fe,Ni). The section also contains seven two-phase and three three-phase regions. The S content of the monosulfide solid solution attains 50.8 at. % at Ni : (Ni + Fe) = 0.6 and 54.0 at. % at Ni : (Ni + Fe) = 0.2. The heazlewoodite solid solution contains up to 26 at. % Fe (at 44.3 at. % S). The highest Ni content of the pentlandite solid solution is 22.5 at. % at 47.5 at. % S and 32.0 at. % at 46.2 at. % S.
