Zusammenfassung:Ti and Y 2 O 3 reaction products find application in flash memory drives, in ODS steels as dispersion strengthening constituent and in Ti castings. The solid state reaction between Ti and Y 2 O 3 , was studied using a suitable experimental setup. The reaction product was investigated by a variety of electron microscopy techniques including SEM, TEM and EBSD. Surface characterisation revealed islands of the reaction product and step like structure for the un-reacted Ti matrix, typical of thermal etching. The reaction product was identified as Y 2 TiO 5 by analysis of selected area electron diffraction pattern.
