Abstract

As part of the study of hard magnetic alloys on the basis of manganese, the impact of titanium and iron in the range up to 5 wt. % on the magnetic hysteretic properties of the 72Mn–27Al–1C hard magnetic alloy is considered. It is shown that upon alloying to 2 wt. %, both Ti and Fe increase the magnetic hysteretic properties of the alloy, and then reduce them. On the 72Mn–27Al–1C–2Ti(Fe) alloys, the maximum energy product (BH)max = 12 kJ/m3 (11,5⋅106 G⋅Oe) was obtained with a residual induction of Br up to 0.36 T (3600 G) and the coercive force НсВ of 110–120 kA/m (1400–1500 Oe), which corresponds to the best Japanese data for these alloys.
