Atomistic mechanisms of the mechanical behaviour of nanostructured silicon carbide films. Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications.

Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications. This project aims to understand the mechanisms behind the exceptional properties in ns SiC and to explore the possibility of realizing the two properties in the same ns SiC. The results obtained from this research will be very important for guiding the structural design of SiC with exceptional mechanical properties which will have a wide range of structural applications.Read moreRead less
