The chemical excess at high angle grain boundaries in yttrium doped alumina was characterized using transmission electron microscopy and energy dispersive spectroscopy. The sample had a bimodal microstructure and one explanation for the fast growth o

Atomic force microscopy was used to measure the dimensions of grain-boundary thermal grooves on the surfaces of Al2O3, 100 ppm Y-doped Al2O3, and 500 ppm Y-doped Al2O3 ceramics heated at temperatures between 1350°C and 1650°C. The measurements were

Bulk phase transformation kinetics were not well understood before Davenport and Bain developed time–temperature-transformation (TTT) diagrams for steel alloys in the 1930s. These powerful diagrams revolutionized the heat treatment of steel and oth

To test the effect of grain boundary energy on the nucleation of a transition from a low mobility to a high mobility grain boundary complexion, polycrystalline yttria-doped alumina was sandwiched between two single crystals of sapphire. Thermal groov

Grain-boundary character distributions (GBCDs) were determined for spark plasma sintered Y- and La-doped aluminas prepared at temperatures between 1450 degrees C and 1600 degrees C. La doping leads to grain boundaries that adopt (0001) orientations 3

The grain-by-grain orientation relationships between an Fe2O3 film, grown using pulsed laser deposition, and a polycrystalline SrTiO3 substrate were determined using electron backscatter diffraction. This high-throughput investigation, we call combin

The thermal groove technique has been used to measure relative grain boundary energies in two 100 ppm Ca-doped yttria samples. The first has a normal grain size distribution and the boundaries have a bilayer of segregated Ca. In the second sample, th
