英文摘要	Fe3Si-based ordered alloys alloyed by Cr and Al were prepared by vacuum arc melting and annealing. The intermetallics were characterized by XRD and SEM. The mechanical property of the alloy was studied by microhardness test, compression test, and bending test. The results show that the main phase of the ordered alloys is Fe3Si. Brittleness of Fe3Si is significantly improved by Al and Cr alloying. Fe65Si25Cr5Al5 alloy exhibits the highest compressive strength and bend strength with lower strain due to its higher order degree compared with the other alloys. The fracture of the ordered alloys shows distinct cleavage fracture character. Fe80Si10Cr5Al5 alloy shows second brittle cleavage fracture feature. The fracture surface of Fe75Si15Cr5Al5 and Fe70Si20Cr5Al5 alloys presents the mixed characteristics of cleavage and quasi-cleavage fracture with some tearing ridges because of the moderate order degree.
