Abstract： A multi-principal elements aloy with high strength and good corrosion resistance was prepared by recrystallization annealing of cold deformed Co36Fe36Cr18Ni8Ti2 at 700∘C and 800∘C The microstructural characteristics of the alloy， such as phase distribution， recrystallization structure and grain boundary distribution，were characterized by electron backscatter diffraction （EBSD），and the mechanical properties of the alloy were measured by static tensile test. The results showed that although the elongation of the 700∘C annealed alloy is low， its tensile strength and yield strength reach 1037.8MPa and 956.1MPa ， respectively. The corrosion resistance of the alloy in the simulated body fluid was characterized by electrochemical workstation and scanning electron microscope （SEM）. The results show that the 700∘C annealed sample has good corrosion resistance，and the surface of the sample after corrosion is uniform. Combined with the mechanical properties， it is suggested that the 700∘C annealed sample has potential as a new medical metal material.
