Title
Atom displacement during in-situ Synchrotron Measurements in TiO2 in Stage III of flash
Conference Dates
March 10-15, 2019
Abstract
We report on in-situ measurements of displacements for Ti and O atoms within a TiO2 unit cell during flash sintering, where one species (O) moves much more than the other. The heart of these investigations is focused on the hypothesis that colossal concentrations of defects, in the form of Frenkel pairs are generated which lead to abnormal kinetics of diffusion and phase transformations. These experiments will continue to provide new information which can be built into atomistic simulations to provide a scientific basis for the flash phenomena.
