The phase equilibria
in the Fe–Cr–V ternary system at 900°C (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 Fe–V edge into the ternary system. As
shown by the present data, at 900°C the field of the σ phase is directed
from the Fe–V side towards the composition of the σ phase of the Fe–Cr
binary edge (which is virtual at that temperature). The solubility of Cr in the
σ phase at 900°C
reaches about 40 at.%.
