Investigating the mechanisms of phase transformation of technologically important ceramics using DFT

Abstract:
It is well-known that water species can diffuse into ceramic lattices which alters their properties. Yitrria-Stabilized-Zirconia (YSZ) is used as turbine blade coatings in its t' phase. Recent studies show presence of water vapor accelerates transformation of t'-YSZ to c-YSZ and t-YSZ. In this work we used first principle calculations to study the role of point defects in kinetics of this phase transformation and effect of water vapor on that.
