The mechanosynthesis of Fe-Co-Sn ternary alloys from initial powder mixtures of composition (Fe50-x/2Co50-x/2) Snx is studied for x <= 33 at.%. Disordered nanocrystalline bcc solid solutions are formed in that way up to Sn contents as large as similar to 20 at.%. The dissolution of Sn in near-equiatomic bcc Fe-Co is unambiguously proven by X-ray diffraction and Fe-57 and Sn-119 Mossbauer spectroscopy. (c) 2011 Elsevier B.V. All rights reserved.
