英文摘要	FeCrAl alloys were widely used in elevated temperature and oxidising environment due to its outstanding oxidation resistance and mechanical property at high temperature. Two FeCrAl alloys with different chemical composition, Fe-22Cr-3Al-3Mo and Fe-22Cr-2Al-5Mo, produced by hot isostatic pressing (HIP), were investigated in this paper. The microstructures of powders of two alloys were characterized. And the microstructures and tensile strength of as-HIP samples of two alloys were characterized and tested. The results showed that the tensile strength and plasticity of Fe-22Cr-3Al-3Mo alloy were both higher than Fe-22Cr-2Al-5Mo alloy at 20, but they were both lower than Fe-22Cr-2Al-5Mo alloy at 500. The precipitation in the Fe-22Cr-3Al-3Mo alloy were mainly fine AlN phase and a small amount of Cr-rich phase in the grains and grain boundaries. The precipitation in the Fe-22Cr-2Al-5Mo alloy was mainly large size oxycarbides of Cr-rich phase. With the decreasing of Al content and the increasing of Mo content, more large sized Cr-rich phases were precipitated in the grain boundaries, which resulted in the poor plasticity of Fe-22Cr-2Al-5Mo at 20. © 2020, Materials Review Magazine.
