BEND DEFORMATION OF WC-Co CEMENTED CARBIDES AT TEMPERATURES UP TO 1273 K.

Abstract

The bend deformation characteristics of WC-Co cemented carbides were investigated in the temperature range from room temperature to 1273 K by measuring load-deflection curves and examining the structural change in relation to cobalt content, tungsten carbide particle size, domain size of binder phase and carbon content. The relation between transverse-rupture strength and deformation characteristics is also briefly mentioned.
