The electronic structure of yttrium aluminum garnet (Y 3 Al 5 O 12) is studied by means of
first-principles local-density calculations. Results on band structure, density of states, partial …

Available deformation data for superplastic yttria‐stabilized zirconia polycrystals with grain
size< 1 µm have been analyzed at temperatures between 1250° and 1450° C as a function …

The tensile creep behavior of two rare‐earth dopant systems, lanthanum‐and yttrium‐doped
alumina, are compared and contrasted in order to better understand the role of oversized …

Final‐stage sintering has been investigated in ultrahigh‐purity Al2O3 and Al2O3that has
been doped individually with 1000 ppm of yttrium and 1000 ppm of lanthanum. In the …
