Feasibility of Developing a Heusler NiMnSn Alloy via Induction Casting Without Controlled Atmosphere

Abstract

We report a systematic investigation of the structural, thermal, and magnetic properties of Ni50Mn37Sn13 Heusler alloy obtained by fusion without controlled atmosphere and annealing. Specifically, we produce Ni50Mn37Sn13 alloy samples by induction casting and characterize them by X-ray diffraction, differential thermal analysis, and magnetometry. Our results bring to light an interesting way to minimize the processing costs of NiMnSn alloy, inherent to vacuum systems and protection with inert gas. Besides, we show that the studied alloy retains the thermal and magnetic properties observed in other processing routes, thus making it a promising candidate for technological applications.
