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（Ａ·ｍ２·ｋｇ－１），和维氏硬度ＨＶ（ｋｇ·ｍｍ－２）间关系的实验规律：Ｈｓｃ＝１．１６＋［（１８９７／ＨＶ）－３．３１］－１（式中系数因合金碳含量不同而异）。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。
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.
