Abstract

In this work anisotropic motion of disconnections at general grain boundaries in SrTiO₃ was detected in-situ at 1030 °C, 1040 °C and 1050 °C using transmission electron microscopy. The same anisotropic motion of ledges and terraces at the surfaces of SrTiO₃ was detected in-situ. These results corroborate previous ex-situ studies on disconnection motion in SrTiO₃, and experimentally confirm that anisotropic disconnection motion is the mechanism of grain growth.
