摘要
High temperatures solid-liquid equilibria in the Cr-Nb-Si system are poorly known in the Si-rich area ( > 20% at Si). In this study, twenty-two as-cast samples were prepared and fully characterized using X-ray diffraction, scanning electron microscopy and quantitative energy dispersive spectrometry. Obtained results lead us to propose a new schematic layout of the liquidus projection of this system.
