MnAl alloys are very promising rare-earth-free permanent magnets. Nanocrystalline
microstructures can have beneficial effects on the properties of magnetic MnAl alloys. In the …

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 …

This study shows the possibility of dramatically tuning microstructure and magnetic
properties of gas-atomized Mn 54 Al 46 particles by milling for an unprecedented duration of …

Prealloyed powders of Mn 54 Al 46 were mechanically milled, and the as-milled powders
subsequently annealed at temperatures from 350 to 600 C to produce the ferromagnetic L 1 …

Abstract Gas-atomized Mn 54 Al 46 particles constituted nominally of only ε-and γ 2-phases,
ie no content of the ferromagnetic L1 0-type τ-phase, have been used to study the evolution …

The influence of an additional annealing step during synthesis on the preparation of MnAl
based permanent magnet alloys has been investigated. Bulk samples of Mn 55 Al 45 C 2 …

Pre-alloyed Mn50+ x− yAl50− xCy (x= 0, 2, 4, 6, 8; y= 0, 1.7, 3) powders were mechanically
milled (MM), and the as-milled powders subsequently annealed at temperatures from 350 to …

MnAl alloys are attractive candidates to potentially replace rare earth hard magnets because
of their superior mechanical strength, reasonable magnetic properties, and low cost. In this …

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 …

Ferromagnetic phase of Mn-Al exhibits great potential in the rare-earth free permanent
magnetic materials due to its high magnetocrystalline anisotropy, high magnetization, high …
