Determination of the Local Phase Diagram in WC-(Ni-Fe)Pseudo-Binary System

    Graphical Abstract
    • Abstract
  • The characteristics of local phase diagram in WC-(Ni-Fe)pseudo binary system were studied by means of optical microscope,SEM,X-ray diffraction and thermal-analysis.The maximum solubility and the solubility at room temperature of WC in γ phase were also measured.The results show that WC-(Ni-Fe)pseudo binary system is still a typical WC-(Ni-Fe)eutectic phase diagram.The eutectic temperature is 1419℃.The solubility of WC in γ phase varies with temperature.The maximum solubility at eutectic temperature is 11.2% and the solubility at room temperature is 9.01%.
