Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied...

grain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size....

according to size. Significant energy is usually required to disintegrate soil, etc. particles into the PSD that is then called a grain size distribution...

known as grain boundaries. Crystallite size in monodisperse microstructures is usually approximated from X-ray diffraction patterns and grain size by other...

barley groats. The grain is cleaned, sorted by grain, size and peeled (if necessary) before being hulled. Additionally, the grains can be sliced on a...

In materials science, grain growth is the increase in size of grains (crystallites) in a material at high temperature. This occurs when recovery and recrystallisation...

particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer...

In parallel computing, granularity (or grain size) of a task is a measure of the amount of work (or computation) which is performed by that task. Another...

of these dislocations. Whatever the mechanism may be, (work hardening, grain size reduction, etc.) they all hinder dislocation motion and render the material...

deformation. Initial grain size affects the critical temperature. Grain boundaries are good sites for nuclei to form. Since an increase in grain size results in...

magnification microscopy. Physical characteristics include colour, texture, grain size, and composition. Lithology may refer to either a detailed description...

grain size, grain shape, and composition. Sediment size is measured on a log base 2 scale, called the "Phi" scale, which classifies particles by size...

conductivity. To yield the desired bond area, temperature and initial grain size are precisely controlled over the sintering process. At steady state,...

the materials sizes and tests regarding sandpaper and other similar coated abrasives. It has three parts: ISO 6344-1:1998: Grain size distribution test...

physical size of the abrasive grains in the wheel. A larger grain will cut freely, allowing fast cutting but poor surface finish. Ultra-fine grain sizes are...

form a granular material (see also grain size). There are several methods for measuring particle size and particle size distribution. Some of them are based...

already achieves uniform elongations of 0.3 with a grain diameter of 200 μm. With increasing grain size, both the Lüders strain and the Lüders effect decrease...

framework grains and the abundance of a muddy matrix between the larger grains. Composition of framework grains The relative abundance of sand-sized framework...

typewriter, should be fed grain edge first so that the axis of the rollers is along the grain. Traditionally, a number of different sizes were defined for large...

hydraulic conductivity is correlated to soil properties like pore-size and particle-size (grain-size) distributions, and soil texture. In the experimental approach...

gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. Soil gradation is...

changed: the grain size, the grain size disposition and the grain shape. Milling also refers to the process of breaking down, separating, sizing, or classifying...

Wheat is a grass widely cultivated for its seed, a cereal grain that is a staple food around the world. The many species of wheat together make up the...

as a crystallite (grain) size below 100 nm. Grain sizes from 100 to 500 nm are typically considered "ultrafine" grains. The grain size of a NC sample can...

reduction of grain size in the ultrafine range from 100 to less than 500 ums. Further grain refinement to nanocrystalline structure with grain size less than...

particles violently collide, resulting in a reduction in grain size and production of fine grained ash particles. In addition, ash can be produced during...

certain energetically favorable grains (crystallites) grow rapidly in a matrix of finer grains, resulting in a bimodal grain-size distribution. In ceramic materials...

intrinsic activation energy and a weaker dependence on grain size. As grain size gets smaller, grain boundary area gets larger, so dislocation motion is...

can cause order of magnitude differences in grain size. Some specially processed aluminium alloys have grain diameters which are hundreds of nanometres...

microstructure of small crystals called "grains" or crystallites. The nature of the grains (i.e. grain size and composition) is one of the most effective...
