WebAug 25, 2013 · That could be compensated for by calculating patterns with varying values of the March-Dollase orientation parameter (Dollase 1986). Another factor is the sample itself. It may not be pure, it may have minor amounts of another polymorph, and, especially when sample sizes are marginal, signals from the sample presentation system, such as ... WebSep 25, 2012 · Two LPOs were analyzed: a random orientation distribution function and an orientation distribution function with strong directional crystalline texture generated from a March–Dollase distribution. Three SPOs were considered: equiaxed grains; elongated grains and a mixture of equiaxed and elongated grains.

WebApr 6, 2024 · Electron backscatter diffraction (EBSD) further reveals that most grains of the textured PZT ceramics are oriented along the <001> direction (fig. S4), where the volume fraction of oriented grains (f) was found to be 94 to 95% for PZT textured ceramics by fitting the 00l pole figure data to the March-Dollase texture model. WebThe March model [Dollase (1986). J. Appl.
