Transition-metal (TM) carbides are an important class of hard, protective coating materials; however, their brittleness often limits potential applications. We use density functional theory to investigate the possibility of improving ductility by forming pseudobinary cubic M1M2C alloys, for which M1 = Ti or V and M2 = W or Mo. The alloying elements are chosen based on previous results showing improved...
The physical properties of hard and superhard nanocomposite thin films are strongly dependent on their nanostructure. Here, we present the results of an investigation of nanostructural evolution and the resulting mechanical properties of (Zr1−xSix)Ny films, with 0⩽x⩽1 and 1⩽y⩽1.27, grown on MgO(001) and Al2O3(0001) substrates at temperatures Ts=500–900°C by reactive magnetron sputter deposition from...
