| Outline of Final Research Achievements |
The investigation of ultra-high temperature mechanical property of power semiconductors and heat-resistance ceramics is an important issue. Currently, the highest temperature used for nanoindentation tests is a few hundred degree. In this study, to realize ultra-high temperature nanoindentation up to 1200 degree, local heating method using a beam of laser was used to heat the samples. It was found that the nano-crystal diamond indenter was able to be used for the nanoindentation of ultra-hard materials like diamond, and by momentary local heating, the thermal deformation of the indentation system was suppressed.
