Effect of deformation nanostructuring and following annealing on phase composition evolution of invar alloy Fe-36%Ni

R.R. Mulyukov, I.K. Bitkulov, I.Z. Sharipov


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.
