A Study of Grain Morphology in Ultrafine Grain Size Metals and Alloys.
Abstract
Grain morphologies, as defined by the rigorous techniques of quantitative microscopy, were investigated for ultrafine grain size 1010 modified steel and titanium alloys. Microstructures were defined by optical, transmission electron, and scanning electron microscopy techniques. Dihedral angles around three grain triple points, sides per grain, mean grian intercepts, grains per unit area, homogeneity of microstructure and hardness were investigated as a function of processing history. The microstructural characteristics undergo a fundamental change as the mean grain intercept is reduced to submicron dimensions. (Author)
