| 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?" |
