摘要：
Constituent phases, melting behaviors, and microstructure of multicomponent (Fe(0.5)Co(0.5)) (x) (Mo(0.1)C(0.2)B(0.5)Si(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 Fe(3)C- and Cr(23)C(6)-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 microstructural formation of other multicomponent alloys with similar microstructures by artificially adjusting the composition.
