Grain size, size-distribution and dislocation structure
Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size-distribution and dislocation structures. Physically based theoretical functions and their Fourier coefficients are available for both, the size...
متن کاملEffects of Varying Methodologies on Grain Particle Size Analysis
Particle size reduction is an important component of feed manufacturing that impacts pellet quality, feed flowability, and pig feed efficiency. The correct determination of particle size is important for feed manufacturers, nutritionists, and pork producers to meet target specifications. The current method for determining the geometric mean diameter (dgw) and geometric standard deviation (Sgw) ...
متن کاملSpatial analysis of grain size in Santa Monica Bay.
Maps are useful scientific tools for presenting environmental information, but the statistical techniques necessary to prepare scientifically rigorous maps have primarily focused on terrestrial habitats. This study compares three popular techniques (triangulation, kriging, and co-kriging) to map sediment grain size in Santa Monica Bay, California. Two grain size data sets, one collected in 1994...
متن کامل27. Data Report: Grain-size Analysis of Sediments
Ocean Drilling Program (ODP) Leg 156 examined hydrological, geochemical, structural, and sedimentological processes at the toe of the northern Barbados accretionary prism (Shipley, Ogawa, Blum, et al., 1995). As part of this program, more than 400 samples were collected from Sites 948 and 949 for grain-size analysis. The primary objective of these analyses was to accurately determine weight per...
متن کاملAverage Grain Size Determination Using Mathematical Morphology and Texture Analysis
Many industrial processes need information about material grain size. In this work we examined rolled chrome concentrate to determine the average grain size. Test material was sieved into 15 fractions, from 37 μm to 500 μm. The analysis method can be divided in three sections: preprocessing, feature extraction and classification. Mathematical morphology was used as preprocessing method, with gr...
