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 …

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 …

Melt spun ribbons of Mn53Al45C2 and Mn52Al46C2 have been synthesized by rapid
quenching of the melt with the purpose of monitoring the ε-τ phase transformation to show …

The MnAl-base permanent magnets continue to loom on the horizon as potentially important
technological materials. Marginal enhancement of their technical magnetic properties and …

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 …

In-magnetic-field annealing (IFA) effects on Zn-modified Mn-Al and Mn-Al-C were
investigated at the annealing temperature of 573 K, which was around their TC. Mn 53 Zn 2 …

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 …

The phase formation of ferromagnetic L1 0-MnAl (τ-phase) was accelerated by annealing in
magnetic field. With in-field annealing at 623 K, the magnetization of the τ-phase annealed …

In order to understand the genesis of the magnetic τ-phase of MnAl alloy, which due to its
multiphase nature is generally difficult to synthesize as a single-phase, we have synthesized …

Mn54Al44C2 ribbon samples have been prepared by melt spinning in a single-phase ɛ
hexagonal disordered state and its exothermal transformation at around 500° C into a …
