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 …

Combined accelerating effects of ε–τ phase transformation by in-magnetic-field annealing
and Zn-addition were investigated for Mn 53 Zn 2 Al 45 in magnetic fields up to 15 T. The in …

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 …

Differential thermal analysis (DTA) on quenched Mn 55 Al 45 with hcp structure (ε-phase)
was performed under magnetic fields up to 15 T in order to investigate the magnetic field …

The phase formation of ferromagnetic L1 0-MnAl (τ-phase) was accelerated by annealing in

Mn 54− x Al 43 C 3 Zr x (x= 1, 3) alloys were prepared by rapid solidification followed by
heat treatment to produce the ferromagnetic τ phase. The substitution of Zr for Mn in the …

Mn–Al–C is intended to be one of the “gap magnets” with magnetic performance in-between
ferrites and Nd-Fe-B. These magnets are based on the metastable ferromagnetic τ-phase …

Mn-Al-C system offers a possibility of rare-earth-free permanent magnets with the reduced
temperature-dependent deterioration of magnetic properties. The Mn-Al-C alloy composition …
