Abstract
The solubility limit of Cr in Fe (a-Fe-Cr) at lower temperatures is a matter of debate. We report a direct estimation of the solubility limit at 300°C from SANS data obtained for neutron-irradiated Fe-Cr alloys. The SANS results indicate that the equilibrium concentration of a was reached via irradiation-enhanced diffusion. The solubility limit was estimated using an iterative approach based on the SANS invariant and the lever rule of phase equilibrium
