对FeNiCrAl合金显微组织和力学性能的研究表明：[Ni]/[Cr]0．9（摩尔比）的合金以γ相为基体，[Ni]/[Cr]（摩尔比）＝0．6～0．8和0．6的合金分别以γ十α双相和α相为基体，合金在不同温度热处理后，由于相的析出或溶解，显示出不同的力学性能．
The study on the microstructure and mechanical properties of FeNiCrAl alloy shows that the [Ni] / [Cr] 0.9 (molar ratio) alloy is based on γ phase with [Ni] / [Cr] ~ 0.8 and 0.6 of the alloy respectively gamma ten α and α phase matrix, the alloy at different temperatures after heat treatment, due to precipitation or dissolution phase, showing different mechanical properties.
