WC-(Ni-Fe)伪二元系局部相图的测定

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

    摘要
  • 摘要: 用光学显微镜、电子显微镜、图像仪、X射线衍射相分析、热差分析等综合方法,研究了WC-(Ni-Fe)系合金,在WC含量(质量分数为6%~38%)范围内的伪二元系相图特征.同时研究了WC在γ相中的最高溶解度和室温溶解度数据.结果表明,WC-(Ni-Fe)伪二元系相图仍属于典型的二元共晶型相图,γ相中的溶解度随温度而变化,共晶温度下最大溶解度(质量分数)为11.2%,室温时最大溶解度为9.01%.

     

    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%.
