摘要：

Herein, the Co30Ni30Fe30Zr10 eutectic multi-principal element alloy is prepared by vacuum arc melting. The phase composition and microstructure of eutectic alloy are analyzed by X-ray diffraction (XRD) and scanning electron microscope (SEM). It is showed in the results that the eutectic multi-component alloy is composed of primary phase and eutectic structure, in which the primary phase is Fe-rich phase, and the eutectic structure is mainly composed of face-centered cubic (FCC) and body-centered cubic (BCC) phases. Co30Ni30Fe30Zr10 eutectic multi-component alloy possesses good room-temperature mechanical properties. Its yield strength, compressive strength, and compression ratio are 700, 1000 MPa, and 22%, respectively.
