Phase-pure τ-MnAlC powder has been synthesized using mechanical alloying followed by a
single annealing step. Mechanical alloying from the elemental constituents resulted in 100 …

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 …

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 …

The phase transformation in two modes, including both displacive and massive growth of τ-
phase from ε-MnAl (C), was observed by in situ transmission electron microscopy. The exact …

The effects of elemental doping of Si and Fe on the ε→ τ phase transformation and the
magnetic properties of MnAl were studied. The magnetic powders of Si-and Fe-doped MnAl …

We have prepared supersaturated-solution Mn-Al-C alloy powders by mechanical alloying
using a planetary high-energy mill. The starting materials were pure Mn, Al and C powers …

High density MnAl–C magnets with enhanced coercivity and remanent magnetization were
prepared by high-pressure compaction of the\uptau τ-phase obtained by annealing the as …

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 …

In this study, detailed microstructural characterisation has been conducted in both as-
transformed and hot deformed samples of τ-MnAl-C using transmission electron microscopy …

Bulk MnAl-C magnets were prepared via high-pressure compaction of melt-spun ribbons.
The ε→ τ phase transformation (PT) in the melt-spun MnAl and MnAlC ribbons occurs mainly …
