;Schematic diagram of binder damage in multi-ligament zone of WC-Co alloy[24] 2.1 裂纹断裂路径 在研究合金断裂机理的过程中,很多研究者都同时研究其断裂路径.GURLANA[25]认为无论是低Co还是高Co合金,断裂都有避开Co相的倾向,多发生在碳化物相和WC-WC边界上.当WC晶粒尺寸不超过1~2 μm时,裂纹仅分布在...带中也会出现微孔和空洞[31].钝的裂纹尖端和内部孔隙的长大和合并会导致韧带破裂,裂纹失稳.韧带区的长度大致为合金碳化物平均自由程的5倍,EVANS等[32]将其称为多韧带区. 图2 WC-Co裂纹传播路径[28] Fig. 2 Crack propagation path of WC-Co alloy[28] 2.2 硬质合金的疲劳裂纹扩展模式 硬质合金的疲......
