Summary:Herein, the Co 30 Ni 30 Fe 30 Zr 10 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. Co 30 Ni 30 Fe 30 Zr 10 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.
