DESCRIPTION:In order to clarify the deformation and fracture mechanism in o
 xides such as Al2O3 and STO\, TEM in situ nanoindentation experiments were
  conducted for their single crystals and bicrystals. We successfully obser
 ved the dynamic behavior of twin formation\, twin-GB interaction\, pile-up
  dislocation\, jog and kink formation and jog drag dynamics and so on. The
  mechanism of each dynamic behavior will be discussed in detail in this pr
 esentation. GB migration plays an important role in considering the high t
 emperature mechanical properties. Recently\, we have found that GB migrati
 on behavior in Al2O3 can be precisely controlled by the aid of the high-en
 ergy electron beam irradiation. This technique was applied to directly vis
 ualize the atomistic GB migration. It was revealed that the GB migration i
 s processed by a cooperative shuffling of atoms in GB ledges along specifi
 c routes. References [1] S. Kondo\, T. Mitsuma\, N. Shibata\, Y. Ikuhara\,
