| 摘 要： | 对硬质合金磁性能与显微结构参数之间的关系模型进行了简短介绍。测量了超细、亚微和中粗晶粒度WC-Co硬质合金的磁性能,并利用扫描电镜或金相显微镜测量对应牌号合金的WC平均晶粒度,建立了一个新的描述WC-Co硬质合金磁性能和平均晶粒度之间的经验关系公式。结果表明,新关系式对于不同合金牌号合金具有较高的准确度和良好的应用效果。

| Abstract: | The relationship model between magnetic properties and microstructure parameters for WC/Co cemented carbide is simply introduced.The magnetic properties of ultrafine,submicron and middle-coarse grained WC/Co cemented carbide were measured.The average grain sizes of WC were characterised by using scanning electron or metallographic microscope.A new empirical equation between the magnetic properties and the average grain size of WC for WC/Co hardmetals was established.The result shows that the new empirical e... |
