Measurement of fracture toughness of cemented carbides

Popis výsledku v původním jazyce

Cemented carbides represent a class of materials whose high hardness and wear resistance, even at temperatures up to approximately 650 °C, surpass those of other materials. These properties are given by their composite structure, which consists most often of tungsten carbide (WC), and metal matrix, typically cobalt. The combination of hard carbides and a soft binder provides a synergic effect which is beneficial to their properties. Related to the high hardness of cemented carbides is the decrease in fracture toughness, an aspect which is very important to cutting tools. It is therefore necessary to measure fracture toughness, and thus monitor the condition of the material. The present tests were concerned with three types of cemented carbides which are used for making cutting tools.
