| Outline of Final Research Achievements |
The purpose of this study is to develop the rheological microscope, which is based on the principle of the electro-magnetically spinning viscometer. In the system, multiple small metal particles are dispersed in the sample and their rotational velocities are observed through the image analysis, giving the information on the distribution of the rheological properties. We successfully developed a system, in which aluminum spheres with diameter of 0.5 mm are employed as probes for local mechanical properties. To apply the system for the extra ordinal circumstances such as high temperature and high pressure, we developed a torque range extender. Also we obtained an idea to use punched substrate as the source of the mechanical momentum. We could observe the diffusion of the momentum from a small hole, which is the direct image of the mapping of the rheological properties.
