Stable ranges concerning composition and temperature have experimentally been determined for the intermetallic compounds in the ternary Fe-Cr-Mo system. The existence of stable and intermediate R-phases in the ternary alloy is confirmed and the relation with that in the Fe-Mo binary alloy is experimentally established. The χ -phase does not exist above 1473 K (1200°C). The isothermal sections of the equilibrium phase diagram in the Fe-Cr-Mo ternary system at 1523 K (1250°C) and 1123 K (850°C), which are different in part from those shown in the literature, are proposed.
