Abstract
Fatigue lifetimes and crack growth behavior of the cemented carbides with different Co content were investigated. Effect of the Co content on the fatigue lifetimes is found to be minimal within the Co content, 13 –18 wt% tested in the present study. At the high Kmax region, the crack growth resistance for the WC-18 wt%Co is higher than that for the WC-13 wt% Co. In the lower Kmax region, the reverse trend, i.e., the crack growth resistance for the WC-13 wt% Co is higher than that for the WC-18 wt%Co, was expected, but this point remain obscure due to the lack of the experimental data.
