Abstract

Abstract

A study on microstructures and mechanical propertiesin 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 and 0.6 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.
