| Research Abstract |
In order to develop shape memory materials working at high temperature in air, the microstructure of nano particle of pure zirconia and shock consolidation have been investigated. The average diameter of the raw pure zirconia nanoparticle used in this study is approximately 50nm and the microstructure consisted of fully monoclinic phase. In those nano particles, the (100) compound twins have also observed. Additionally, partly consolidation of pure zicronia has been succeeded by shock compaction.
