Resum
The fracture and fatigue phenomena in WC-cobalt cemented carbides (hard-metals) have been subjects extensively investigated in the last 30 years. From these studies, it is well established that the metallic binder phase plays a key role as the toughening and fatigue-susceptible agent in these materials, as its effective ductility is critical for defining crack-growth resistance and cyclic-induced degradation. However, experimental proof of the role of toughening and fatigue micromechanisms has u...
