Abstract

Constituent phases, melting behaviors, and microstructure of multicomponent (Fe_0.5Co_0.5)_x-(Mo_0.1C _0.2B_0.5Si_0.2)_{100 x} alloys (x = 95, 90, 85, 80, and 70) produced by copper mold casting were evaluated by various analysis techniques, i.e., X-ray diffractometry, scanning electronic microscopy with energy dispersive X-ray spectrometry, and differential scanning calorimetry. Metastable Fe₃C-and Cr₂₃C₆-type phases were identified in the chill-cast alloys. A schematic illustration was proposed to explain the evolution of constituent phases and microstructure for the alloys with x = 95, 90, and 85 during the solidification process, which could be applicable to controlling micro structural formation of other multicomponent alloys with similar microstructures by artificially adjusting the composition.
