A study on the mechanical behaviour of WC/Co hardmetals
The hardmetal cutting tools used in machining are submitted to extreme conditions in terms of temperature and mechanical loading. A better understanding of the failure of cutting tools and capability to predict tool life are key factors in the development of new tool materials with improved mechanical behaviour. Main failure mechanisms are wear, thermal–mechanical fatigue and brittle fracture. ...
متن کاملDiffusion bonding of hardmetals (WC-Co) with metallic interlayers
Diffusion bonding of hardmetals (WC-Co) to themselves or with other metallic material (mildsteel) has been evaluated in the present paper. Metallographic studies and mechanical tests have been used to determinate the influence of the bonding parameters (temperature, pressure and time) on the bond microstructure and strength. Different metallic interlayers applied in form of thick foils were use...
متن کاملThermophysical properties of Co-free WC-FeCr hardmetals
Fe-Cr alloys can potentially replace carcinogenic Co as the binder system in WC-hardmetals. Furthermore, they may be used in emerging applications such as nuclear fusion reactor shielding, where use of Co is forbidden due to the formation of hazardous activated species. In such applications, a good understanding of thermophysical properties is critical to predicting high temperature performance...
متن کاملThermally induced surface integrity changes of ground WC-Co hardmetals
Ground hardmetals are exposed to high temperatures during both processing (e.g. coating deposition) and use (e.g. as a cutting tool). However, studies on thermally induced changes of surface integrity are limited. Here we address this by means of FIB/FESEM and EBSD investigation, with special focus on the binder phase characterization. Our findings indicate that thermal treatment causes two mai...
متن کاملFRACTURE AND FATIGUE BEHAVIOR OF WC-Co AND WC-CoNi CEMENTED CARBIDES
The fracture and fatigue characteristics of several cemented carbide grades are investigated as a function of their microstructure. In doing so, the influence of binder chemical nature and content (Co and 76wt%Co-24wt%Ni), as well as carbide grain size on hardness, flexural strength, fracture toughness and fatigue crack growth (FCG) behavior is evaluated. Mechanical testing is combined with a d...
