The phase transformations of invar alloy Fe-36%Ni nanostructured on Bridgman anvil during annealing were analyzed. Based on the results of the analysis previously detected non-monotonic behavior of the coefficient of linear thermal expansion and the emergence of a ferromagnetic state above the Curie temperature of Invar are explained.
