Temperature dependencies of saturation magnetization and temperature coefficient of linear expansion for the Fe-36%Ni alloy have been studied in different structural states obtained by severe plastic torsion straining under quasi-hydrostatic pressure and following annealing at different temperatures. The studies have revealed the decrease in the coefficient of thermal expansion for the invar alloy within the temperature range 20-100 °C¡ from severe plastic deformation, as well as the generation of superlattice segregation in it. |
