In-situ neutron powder diffraction studies of phase decomposition in novel mixed carbide systems
Cemented carbides are composite materials manufactured via powder metallurgy. The excellent wear resistance, high hardness, and high toughness make them widely used materials in cutting and drilling tools. In order to develop cemented carbides with enhanced mechanical properties and reduced cost, our current research interests are oriented on the novel carbide mixtures for the replacement of WC. We have previously shown that the mixed transition-metal carbide phases, e.g. (Ti,Zr)C, with a miscibility gap decompose during the sintering. The formed lamellar structure enhances the hardness of the final product. Our ex-situ XRD results show that the addition of NbC affects the decomposition kinetics, allowing the control of microstructure evolution at sintering temperatures. In order for us and our industrial collaborators to gain a better understanding of the diffusion-driven microstructural evolution of NbC and WC doped novel (Ti,Zr)C mixtures, we propose the first in-situ neutron powder diffraction experiments of (Ti,Zr)C based carbide mixtures during the thermal treatments at 1600 °C.
