Expanding Horizon of Superplastic Nano-materials

Superplasticity refers to an ability of nano-grain polycrystalline materials to exhibit exceptionally large elongation just like a chewing gum. Superplastic forming provides wonderful opportunities for the technology of structural/functional ceramics, composites, and oxide superconductors. Novel and useful properties of nanocrystalline materials are also expected to arise from interface phenomena.

High Strain Rate Superplastic Metal Matrix Composites

Metal matrix composites (MMCs) show poor workability because of low ductility and the demerit limits application of MMCs. The aims of this work are development of high strain rate superplastic MMCs and investigation of superplastic deformation mechanisms of MMCs to improve upon poor work-ability. Achievement of this work will promote application of MMCs because high strain rate superplasticity enables near-net shape forming with high productivity.

Fabrication and Mechanical Research of Fiber Reinforced Ceramics

Fiber reinforced ceramic composites have been developed for the purpose of improving brittleness. Several fabrication methods as mechanical well as design of fiber reinforcement properties are investigated.
