The ferromagnetic MnAl-C powders were prepared by using a one-step solid-state reaction
method starting from Mn micro-/nano-particles and Al/C micropowders. The bulk MnAl-C …

MnAl is a promising rare-earth free permanent magnet for technological use. We have
examined the effects of consolidation by back-pressure, assisted equal channel angular …

Isotropic nanocrystalline MnAlC particles with quasi-spherical shape were synthesized by
gas-atomization being afterwards milled for a short time of 60 s. Gas-atomized and milled …

In order to improve the hard magnetic properties of MnAl alloy, it is critical to fabricate fine τ
