Abstract

Experimental results on a 2 mol% yttria-stabilized tetragonal zirconia (2YTZ) reveal that grain growth is accelerated by Al segregation to boundaries even in the absence of an amorphous grain boundary phase. This is consistent with an analysis of Coble diffusion creep indicating an increase in grain boundary diffusion coefficient with the segregation of Al to grain boundaries.
