Probing Chemical Order in FeNi Alloys
Abstract: A promising candidate for low-cost, high performing permanent magnet materials is the chemically ordered L10 FeNi compound. This phase is only observed naturally in select meteorites, and is notoriously difficult to form on laboratory time scales due to very low atomic motilities. Currently, artificial synthesis has only been achieved in ultrathin films or in irradiated materials. However, recent neutron diffraction studies carried out by our group has demonstrated evidence of a chemically disordered tetragonal (A6-type) phase in FeNi, which is proposed to be a transitional phase linking chemically disordered FeNi with chemically ordered L10 FeNi. To pursue this work, bulk alloys of doped FeNi were subjected to severe plastic deformation followed by a specialized annealing procedure using a custom built furnace; this is hypothesized to promote the formation of the A6 and L10 FeNi phases.
