PACS numbers: 61.05.Qr, 61.72.Hh, 75.30.Cr, 75.50.Bb, 76.80.+y, 81.20.Wk, 81.30.Kf, 81.40.Rs

The influence of mechanical alloying in a ball mill for a fixed time of 4, 8, 12 and 16 hours on the structure, distribution of hyperfine magnetic fields and magnetic properties of Invar Fe–30.9% Ni–1.23% C alloy is studied. Mechanical ball milling of the alloy powder causes both a direct ???-transformation and a reverse ???-transformation with the increasing duration of treatment, which lead to changes in the magnetic subsystem. As a basis of staging of these transformations in the alloy during mechanical ball milling, there is redistribution of chemical elements in a solid solution induced by deformation, including partial decomposition of graphite fraction and an additional dissolution of carbon in austenite phase.
