Abstract

This article analyzes the fatigue behaviour of some cemented carbides based on tungsten and titanium carbide. It is shown that the performance of carbides in cyclic loading conditions is controlled by the fatigue sensitivity (slope of Wöhler curve) and plasticity of an alloy. The scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD) studies revealed that the fatigue damage is preceded by the plastic strain taking place in both phases − in the ductile binder and in the brittle carbide (WC, TiC).
