    摘要:

    探讨了硬质合金的硬度、矫顽力同合金显微结构和成分的关系,得到了两相高碳WC-Co硬质合金的比矫顽力Hsc,和维氏硬度HV间关系的实验规律;Hsc=1.16+「(1897/HV)-3.31」^-1。论述了有关物理基础,讨论了用Hsc对WC-Co合金的HV进行评估的可能性。

    Abstract:

    The relations of the Vickers-hardness HV and the specific coer.cive force Hsc withmicrostructure and composition of WC- Co cemented carbides have been explored. The experimental regularity of the variety of the specific coercive force Hsc(A.m2. kg-1)with theVickers hardness HV (kg.mm-2)for two-phase and high- carbon WC-Co cemented carbides has been attained,which is: Hsc = 1.16+[ (1897/HV)-3.31]-1.The correspondentcoefficients of above expression vary with the carbon content.The possibility of evaluatingHV of WC-Co alloy by Hsc is discussed.
