Abstract Scope |
The L10 structured τ-phase of the Mn-Al-C system gained interest for the potential use as a rare earth (RE) free hard magnetic material. Warm extrusion is a promising route to optimise the extrinsic magnetic properties of MnAl-C alloys; however, the high stresses involved reduce the lifetime of the extrusion tools, which in turn raises the production costs [1]. It has been reported that Cu addition can reduce the force needed for extrusion without negatively affecting the magnetic properties [1] but the mechanism behind this effect was not shown. In the current work, the effect of Cu additions on the microstructure, mechanical and magnetic properties of MnAl-C alloys in various states has been investigated in detail.<br>
