摘要: Abstract Recent advances in microscopy techniques have made possible the quantitative examination of Co binder phase WC–Co cemented carbides [1]. The composition is interest with respect to applications where fracture toughness and fatigue are particularly important. A previous work has observed that hcp/fcc ratio can change applied stress [2]. This part a wider study examining role mean free path, WC grain diameter (dWC) on hcp–fcc content extracted from wide range samples an average dWC 0.6 μm  belongs Special Issue International Conference Science Hard Materials (ICSHM10).
