摘要
根据烧结过程中Ｗ元素的质量守恒，推导出ＷＣ—Ｃ硬质合金中ＷＣ相和η１相（Ｗ３ＣＯ３Ｃ）含量间的关系式，进而导出ＷＣ相和η１相间的相对Ｋη１ＷＣ值表达式，从而建立了一种用Ｘ射线衍射方法定量测定ＷＣ—Ｃｏ合金中η１相含量的实用方法。
The compositional relationship between WC-phase and μ1-phase (Co3W3C) in WC-Co cemented carbides was inferred according to the conservation of W element in the liquid-phase sintering process, and then the expression of relative K value between WC-phase and μ1-phase was inferred further.So that a quantitative and practical X-ray diffraction method for determining μ-phase in WC-Co cemented carbides is established.
