Abstract:
We report on magnetic properties of Fe$_{50}$Ni$_{50}$ and Fe$_{49}$Ni$_{49}$Al$_{2}$ alloys after severe plastic deformation (SPD) by high pressure torsion (HPT) technique. SPD considerably changes the magnetization behavior. The main magnetic characteristics of bulk and HPT materials were determined. Low temperature annealing was used to form the L1$_{0}$ structure. Low temperature annealing at T = 300$^{\circ}$C for t = 1300 hours of plastically deformed Fe$_{49}$Ni$_{49}$Al$_{2}$ alloy leads to an increase in saturation magnetization M$_S$ by up to about 6%. However, it is premature to talk about the formation of even a small amount of phase L1$_{0}$. More research is required.
