Abstract: | Segregation of In in Fe-based alloys containing 0.11–2.12 at.% In has been studied by measuring the perturbed angular correlations
of γ-rays emitted in the nuclear decay of 111In. The probe atoms were introduced into the alloys by either adding the carrier-free 111In during melting or via ion implantation. Ageing of the samples at elevated temperatures followed by a slow cooling to room
temperature allowed us to determine the upper limit of the solubility at room temperature, S(300 K)≤ 30 at. ppm. This value
is far below the one reported in the published phase diagram. Quenching of the samples in water from 973–1373 K resulted in
the determination of the indium solubility in iron at these elevated temperatures.
