Grain Size Distributions in Normal Grain Growth

Practical Metallography, 2010
Abstract An analytical distribution function characterising the grain sizes of polycrystalline microstructures is presented. Contrary to standard mathematical probability functions that are still often used for description of experimentally obtained size distributions, this one is based on a statistical mean-field theory of grain ...

Development of Grain-Size Distributions

1991
Calabrian river-mouth sediments are both bimodal or unimodal. The gravel mode of the bimodal distributions, mostly Rosin-distributed, is interpreted as a first-order element, a primary feature inherited from the jointed and weathered source rocks, whereas the sand mode can be seen as a secondorder element acquired during fluvial attrition. The shape of

Grain Growth in a Microstructure with Bimodal Grain Size Distribution

Physics of Metals and Metallography, 2021
Grain growth in the textureless material characterized by bimodal grain size distribution has been investigated. Grain growth in a pure material can eliminate the second maximum in the distribution, despite the presence of abnormally coarse crystallites in the initial structure.

Fractal Grain Size Distributions

2013
In the previous chapters, we have been concerned with determining grain size, mean grain size or modal grain size. We looked at grain size distributions, number histograms, and volume weighted histograms. The idea was that the grain size distributions were created by physical processes that select or favor one typical grain size.

Genetically meaningful decomposition of grain-size distributions

Sedimentary Geology, 2007
All spatio-temporal grain-size patterns in sediments can be characterized by a mathematical representation of (un)mixing. This implies that an inverse model of (un)mixing would be ideally suited to obtain genetically meaningful interpretations of observed grain-size distributions (GSDs).

Influence of grain size and grain-size distribution on workability of granules with 3D printing

The International Journal of Advanced Manufacturing Technology, 2013
3D printing is a promising method for fabrication of scaffolds. Microporosity is one of the most important properties of scaffolds and directly influences cell attachment, differentiation, proliferation, spreading, resorption, bone ingrowth, and contact.

Impact of grain size and grain size distribution on the resistivity of metal nanocrystalline systems

Computational Materials Science, 2015
Abstract The grain size effect of the resistivity in the metal nanocrystalline systems is known to stem mainly from grain boundaries. In this letter, we propose a semi-quantum model based on transfer-matrix approach to calculate the resistivity. In accord with the above results, the impact of grain size distribution on the resistivity of 2D and 3D ...

Analysis of Grain Size Distributions

AM&P Technical Articles, 2017
Abstract Because the nature of grain size distribution can influence mechanical properties and service behavior, it is important to accurately characterize this parameter. This article demonstrates how to evaluate grain size distribution, which can be done using either grain area or intercept-length measurements.
