ＷＣ－Ｃｏ硬质合金的硬度与韧性关系中有一个最基本的原则，即硬度越高，其断裂韧性就越低。但是发现，在一定的硬度下，其韧性也有一高低变化范围带，可以通过金属成分和显微组织调节改变韧性值。由此，Ｓｃｈｕｂｅｒｔ等人通过细化合金晶粒方法，寻找既有高硬度又有好... WC-Co cemented carbide hardness and toughness of the relationship between the most basic principle, that is, the higher the hardness, the lower the fracture toughness. However, it has been found that under a certain degree of hardness, there is also a range of high and low toughness bands, which can be adjusted by changing the metal composition and the microstructure. As a result, Schubert and others through the fine grain alloy method, looking for both high hardness and good ...
