Developing a new type of covalent binding materials synthesized by processing at the atomic level, we conducted a cooperative research with Germany in quest for novel properties of substances that show high-temperature mechanics (super plasticity in nanoclistalline materials; viscosity flux in amorphous materials) and the outstanding heat-resistant property. Focusing on the covalent binding ceramics, the hardest material, thus, difficult in deformation, we first succeeded in obtaining superplasticity of silicon carbide and achieved high-velocity/low-temperature for superplasticity deformation in grain boundaries of the liquid phase.
By developing a quantitative analysis for the structure of local grain boundaries and chemical binding, which uses the scanning transparent electron microscope (STEM) and the electron beam energy loss spectrum (EELS), we created a model of switching machinery in 3D particles. Moreover, we paved the way for a new area associated with amorphous-state density that utilizes high-temperature deformation and its viscosity flux with systematic studies on the process of synthesizing covalent binding amorphism transformed from polymers. Those studies are expected to give a new direction to the following questions: "How does polycrystal behave when the particles are getting smaller?" "Are they approaching to the property of amorphous solid?"
