FeNiCrAl合金的显微组织和力学性能

Microstructures and Mechanical Properties in FeNiCrAl Alloys

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．

A study on microstructures and mechanicalpropertiesin FeMCrAl alloys was accomplished. The results showed that, when the ratio of equivalent concentrations of M and Cr, [M]/[Cr], was higher than 0.9, the alloys formed γ-phase matrix. The alloys with [M]/[Cr] ratios of 0.6～ 0.8 and0.6 formed α+γ double phases and α -phase matrixes respectively. After treating at different temperature, the phase precipitation or phase dissolution was occured. Alloys were obtained different mechanical properties.
