According to the formation energy of CuS and Cu2S and the solubility formulae of elements Cu and S in ferrite and in austenite, the solubility product formulae of CuS and Cu2S in ferrite and in austenite have been obtained as log[Cu][S]=6.15-5643.78/T , log[Cu][S]=6.15-5643.78/T,log[Cu][S]=6.007-5620.3/T (in ferrite and austenite), and log[Cu]2[S]=6.62-9693.75/T and[Cu]2[S]=6.143-9048.66/T (in ferrite and austenite), respectively, which can be used in concerned research work.
