In the present study, cyclic fatigue tests were conducted on the cemented carbides under the high temperature environment. The tests were performed at two stress ratios, R=0.1 and 0.5. In addition to these cyclic fatigue tests, static fatigue tests at R=1 were also conducted to determine effects of cyclic stress, stress ratio and temperature on the fatigue crack propagation behavior of cemented carbides.
