The objective of this work is to study relationship between oxygen potential and mechanical properties of oxygen nonstoichiometric compound with Ce_<0.9>Gd_<0.1>O_<2-x>. Under high temperature and reducing conditions, oxygen content in Ce_<0.9>Gd_<0.1>O_<2-x> changes and oxygen defect is generated. Therefore Mechanical properties of Ce_<0.9>Gd_<0.1>O_<2-x> can change under such conditions. In our study, we developed new test apparatus for small punch test, which is able to measure mechanical properties under high temperature and reducing conditions. And several tests ran already with this new test apparatus. Advanced investigation would explain how mechanical properties behave in these conditions.
