โฆ Synopsis
Grain growth in two and three dimensions with anisotropic interfacial properties was simulated using the Monte Carlo method. The relative effects of grain boundary energy and mobility anisotropy on number-and area-weighted misorientation distribution functions (MDFs) were compared. Results indicate that energy anisotropy has a measurable effect on misorientation texture development, while mobility anisotropy does not. Qualitatively similar results are obtained in all simulations regardless of dimensionality or crystal symmetry. Microstructures with random orientation texture appear to evolve steady-state MDFs, while those with a preferred orientation do not. Experimentally measured number-and area-weighted MDFs in polycrystalline magnesia are shown to be comparable to those measured in our simulations.

In order to develop a procedure for assessing the growth of interacting surface cracks, the relationship between the area of the crack face and fatigue crack growth behavior was investigated. Fatigue crack growth tests were conducted using stainless steel plate specimens with surface notches. Then,
