Bulk Mn-Al-C magnets have been prepared by hot-compaction, microwave sintering and hot-
deformation. Powders of Mn 53.5 Al 44.5 C 2 alloy in the ε-phase produced by high energy
ball milling have been used as precursor for the hot-compacted and microwave sintered
magnets. Hot-deformed magnets were produced from alloy pieces in the τ-phase. The hot-
compacted magnet exhibits magnetization, remanence and coercivity of 50 emu/g, 28 emu/g
and 3.3 kOe, respectively. Microwave sintered magnet shows a maximum magnetization of …
