| 摘要 | In this study, a magnetic high entropy alloy (HEA) of CoFeMn1.2NiGa0.8 was designed and prepared by arc melting in order to investigate its mechanical, corrosion and magnetic behavior. The results show that the alloy mainly possesses body-centered cubic (BCC) phase and face-centered cubic (FCC) phase. A high compressive strength of 1450 MPa, a strain of 18.5 % and a relatively low yield strength of 303 MPa in as-cast condition at room temperature can be achieved in the present alloy. In-situ high-energy X-ray diffraction technique was employed to reveal the deformation mechanism of CoFeMn1.2NiGa0.8 under uniaxial compression and the results show that the competition between BCC phase and FCC phase plays a significant role during the compressive process. The corrosion behavior of CoFeMn1.2NiGa0.8 was investigated in 3.5 wt% NaCl solution and it turned out that the alloy possessed good corrosion resistance. At last, the magnetic behavior of the CoFeMn1.2NiGa0.8 alloy was studied and it can present a high saturation magnetization of 94.5 emu/g and a coercivity of 26.4 Oe at 4 K. This work indicates that the present CoFeMn1.2NiGa0.8 HEA has promising applications as future magnetic functional materials.
