摘要:A new empirical rule to form single phase solid solution structured high entropy alloys was proposed by integrating three dependent parameters, i.e. atomic size difference delta, mixing enthalpy Delta H-mix and valence electron concentration VEC. It was found that the single phase face centred cubic solid solution will form if delta<4.27%, -7.27 kJ mol(-1)<Delta H-mix<4 kJ mol(-1) and VEC. 8, while the single phase body centred cubic solid solution will form in the case of delta<4.27%, -7.27 kJ mol(-1)<Delta H-mix<4 kJ mol 21 and VEC<6.87. This empirical rule was verified by typical high entropy alloys that have been reported.
