Evolution of magnetic response as a function of annealing temperature in Fe-based alloys

Authorship SCIMAGO INSTITUTIONS RANKINGS

The magnetic response, coercive force and magnetic induction, in Fe-10at.% Si, Fe-6at.% Al-9at.% Si and Fe-4at.% Al-8at.% Ge alloys as a function of the annealing temperature was determined and correlated to the microstructural state. The microstructural characterization was made through differential thermal analysis, mechanical spectroscopy and neutron thermodiffraction studies. It has been determined that the increase in the order degree and the decrease in the mobility of structural defects lead to a deterioration of the magnetic quality of the alloys above detailed.

Keywords
Fe-based alloys; microstructure; Improvement of magnetic properties; Hysteresis loops
