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.
Biography:
Amir Saeidi received his B.S. in Materials Science and Engineering from Shiraz University, Iran, M.S. in Advanced Materials from Ulm Univ., Germany, and is currently a candidate for Ph.D. in Materials Science and Engineering at UC Irvine (expected Fall 2019). Amir’s research interests are in Atomistic Simulations as related to Energy Materials and Catalysts.
