In this work, the effect of carbon addition on the L1 0 τ-phase stability in (Mn 0.54 Al 0.46)
100-x C x (x= 0–5) magnetic alloys are investigated. By microstructural analysis, single …

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 …

The τ-phase MnAl alloys are promising candidate for rare earth free permanent magnets. In
this study, In order to better understand the MnAl ε→ τ phase transition mechanism in a …

The low cost, rare earth free τ-phase of MnAl has high potential to partially replace bonded
Nd2Fe14B rare earth permanent magnets. However, the τ-phase is metastable and it is …

MnAl alloy (τ phase) is one of the most promising rare-earth-free permanent magnets due to
its remarkable magnetic properties. The metastable τ phase is normally produced by rapid …

Abstract Alloys with compositions (Mn 53 Al 45 C 2) 100− x Ni x where x= 0, 0.6, 1.5, 2, 4
and 6 were produced, and the microstructure, magnetic properties and thermal stability of …

The limited coercivity (H c) and metastability of the ferromagnetic τ phase MnAl-C magnet
have constrained its magnetic performance and application potential. Bi was doped into the …

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 …

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 …
