Abstract

Cemented carbides have been utilized as high speed turning tools or heat-resistant tools. So, it is necessary to study fatigue crack propagation behavior of the cemented carbides under high temperature environment in order to understand, or to grasp their capabilities under such a severe environmental conditions. Many studies on static fatigue, on creep and on monotonic mechanical properties of the cemented carbides have been conducted under high temperature environment. However, studies on cyclic fatigue of the cemented carbides under the above environment are very few and limited. In the present study, cyclic fatigue tests were conducted on cemented carbides under 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 study more detail about the effects of cyclic stress, stress ratio and temperature on the fatigue crack propagation behavior of the cemented carbides.
