Phase stability of four different chemical component Fe-Cr-Mn(W, V) alloys are investigated by experimental method and thermodynamic model in this paper. It is indicated that the main phase of four alloys after aged under 623, 673, 773K for 200h are austenitic phase. The results of Thermo-Calc, which are based on Gibbs energy, show that the phases of four alloys under the same temperature as experimental method are single austenitic phase. The results of experimental method and Thermo-Calc agree
