摘要	In this study, the effects of heat treatment at 1000 degrees C celsius and 1100 degrees C on the microstructure and mechanical properties of Co35Cr10Ni43Ti12 medium-entropy alloy (MEA) were investigated, a novel MEA Co35Cr10Ni43Ti12 was fabricated by the technique of powder plasma arc additive manufacturing. The effects of the evolution of microstructure on the mechanical properties were analyzed by XRD, SEM and EBSD. Co35Cr10Ni43Ti12 MEA showed a dual-phase structure of FCC and eta, and the FCC grains exhibited a typical <001> columnar crystal structure along the build direction. After heat treatment at 1000 degrees C, the eta phase was transformed from blocky to plate-like with granular, and after heat treatment at 1100 degrees C, all of the eta phase in the alloy was transformed into plate-like. For the plate-like eta phase, there were 111FCC parallel to{0001}eta and 011FCC parallel to [2 (11) over bar0](eta) orientation relationships with FCC, which were typical N-W orientation relationships. The printed alloy exhibited high tensile strength of 1214 MPa and low elongation of 2.8 %, and after heat treatment at 1000 degrees C and 1100 degrees C, the tensile strength of the alloys decreased to 882 MPa and 807 MPa, respectively, and the elongation increased to 10.6 % and 15.4 %.
