在900 °C等温截面上，Fe固定在70 at.% Ni含量为60 at.%时，通过扫描电子显微镜结合能量色散光谱和X射线衍射测定。在70 Fe-Cr-Ni-Al中只发现一个三相区，标记为α-Fe + β-（Fe，Ni）Al + γ-Fe。对于Fe-Cr-60 Ni-Al截面，存在三个三相区，即，α-Cr + γ-Ni + γ′-Ni 3Al、γ-Ni + γ′-Ni 3Al + β-（Fe，Ni）Al和α-Cr + β-（Fe，Ni）Al + γ′-Ni 3Al以及一个四相区，即α-Cr + β-（Fe，Ni）Al + γ-Ni + γ′-Ni 3Al。在本工作中没有发现季铵化合物。
The 900 °C isothermal sections of the Fe-Cr-Ni-Al quaternary with Fe fixed at 70 at.% and that with Ni fixed at 60 at.% have been determined by scanning electron microcopy coupled with energy dispersive spectroscopy and x-ray diffraction. Only one three-phase region marked as α-Fe + β-(Fe,Ni)Al + γ-Fe has been found in the 70Fe-Cr-Ni-Al section. With regard to the Fe-Cr-60Ni-Al section, there are three three-phase regions, i.e., α-Cr + γ-Ni + γ′-Ni3Al, γ-Ni + γ′-Ni3Al + β-(Fe,Ni)Al and α-Cr + β-(Fe,Ni)Al + γ′-Ni3Al and one four-phase region, namely α-Cr + β-(Fe,Ni)Al + γ-Ni + γ′-Ni3Al. No quaternary compound is found in the present work.
