The objective of this proposed research is to investigate                  fundamental issues concerning the behavior of transformation                    toughened zirconia-based ceramics.  This program includes studies               of: chemical and environmental factors affecting the                            transformation; mechanical behavior -- cyclic loading behavior,                 life predictions under complex loading conditions, strength                     versus toughness relationships, and transformation-induced                      plasticity; and, microstructures and chemistries using x-ray                    (EXAFS and XRD), NMR, internal friction, and FTIR techniques.                   Mechanical property studies will include uniaxial                               tension/compression and triaxial flexure testing.
