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 …

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 Mn-Al-C magnets have been prepared by hot-compaction, microwave sintering and hot-
deformation. Powders of Mn 53.5 Al 44.5 C 2 alloy in the ε-phase produced by high energy …

MnAl (C) is a promising candidate as a rare earth free magnet. When processing MnAl (C) in
laser powder bed fusion (L-PBF) the high cooling rates can retain the high temperature ε …

In this chapter, we are presenting the developments in permanent magnetic materials and
their processing techniques. We discuss different alloy systems, rare-earth (RE) Nd-Fe-B …

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 …

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 …

Ferromagnetic τ-MnAl alloy with attractive magnetic properties has been considered as one
of the most promising rare-earth-free permanent magnetic materials. However, there are …
