Effect of Cu Addition on Structure and Magnetic Properties of CoCrNiFe High Entropy Alloys
The influence of Cu addition on the structural stability and magnetic properties of CoCrNiFe High Entropy alloys were studied by using Monte Carlo method combined with first-principle calculation.The calculation results show that due to the positive binary mixing enthalpy between Cu element and other constituent elements in the alloy,CoCrNiFeCu high entropy alloy forms a short-range ordered structure.The saturation magnetization of CoCrNiFeCu high entropy alloy calculated using a short range ordered structure is 52.2 emu/g,which is more in line with the experimental value(53.4 emu/g)than the result calculated using SQS structure(64.9 emu/g).
