In‐situ measurements of lattice expansion related to defect generation during flash sintering
Abstract
We report results from in‐situ measurements of lattice expansion during flash sintering of 3 mol% yttria stabilized tetragonal zirconia taken at the Advanced Photon Source, Argonne National Laboratory. The expansion is anisotropic, with the relative expansion of the a‐lattice constant exceeding that of the c‐lattice constant. The anisotropic expansion cannot be explained by thermal expansion and is consistent with predictions from ab‐initio calculations based upon the generation of vacancy‐interstitial pairs of zirconium and oxygen.
