The phase equilibria in the FeCrV ternary system at 900C (1173 K) were studied using XRD, metallography and EPMA. The main attention was focused on the character of propagation of the σ phase from the FeV edge into the ternary system. As shown by the present data, at 900C the field of the σ phase is directed from the FeV side towards the composition of the σ phase of the FeCr binary edge (which is virtual at that temperature). The solubility of Cr in the σ phase at 900C reaches about 40 at.%.
