Efficient power-to-work conversion in electric vehicles (EVs) requires soft magnetic materials with low coercivity. Fe-based metallic glasses reduce power losses but struggle achieving casting thicknesses over 1mm due to limited glass-forming ability (GFA). Additive manufacturing (AM), like Laser Powder Bed Fusion (LPBF), provides solutions, with recent studies revisiting Fe-Si-B compositions for processability and performance [1-3]. This study evaluates the alloy Fe74Mo4P10C7.5B2.5Si2. X-ray diffraction (XRD) results of cast plates and ribbons determined the GFA. Thermal properties were analyzed via Differential Scanning Calorimetry (DSC) and Differential Thermal Analysis (DTA), while magnetic properties using Vibrating Sample Magnetometry (VSM). Results suggest the alloy's potential for AM production of soft magnetic components for EVs.[1] Thorsson, L., et al. Selective Laser Melting. Materials & Design.[2] Rodríguez-Sánchez, M., et al.
