Abstract Scope |
The intrinsic magnetic properties of the τ-phase in MnAl-C alloys show strong potential as a rare earth free permanent magnet. Previous works have indicated that Ti and Zr additions may enhance the magnetic properties of melt-spun MnAl and MnAl-C ribbons. The aim of this work is to investigate the effect of Ti and Zr additions on bulk MnAl-C samples in the homogenised, as-transformed and hot-deformed states. The samples were characterised with scanning and transmission electron microscopy and magnetometry. TiC or ZrC precipitates were shown to form and the effect of these on the chemical composition of the τ-phase, its magnetic properties and the flow stress during hot deformation was investigated. |
