Grain-size dependent demagnetizing factors in permanent magnets [PDF]

, 2014
The coercive field of permanent magnets decreases with increasing grain size. The grain size dependence of coercivity is explained by a size dependent demagnetizing factor.

Grain-size distribution of volcaniclastic rocks 1: A new technique based on functional stereology [PDF]

, 2012
The power of explosive volcanic eruptions is reflected in the grain size distribution and dispersal of their pyroclastic deposits. Grain size also forms part of lithofacies characteristics that are necessary to determine transport and depositional ...

Influence of grain size on strength of polymineralic crystalline rock: New insights from DEM grain-based modeling

Journal of Rock Mechanics and Geotechnical Engineering, 2021
Grain size effect on rock strength is a topic of great interest in geotechnical engineering. A consensus obtained from earlier laboratory tests is that rock strength generally decreases with the increase of grain size for both silicate and carbonate ...

Grain size reduction strategies on Eurofer

Nuclear Materials and Energy, 2018
One of the options currently taken into account for the realization of the first DEMO reactor is the “water-cooled blanket”. This option implies a minimum irradiation temperature for the blanket material in the range of 280–350 °C.

Sensitive Grain-Size Components of Last Glacial Loess on Chinese Loess Plateau and Their Response to East Asian Winter Monsoon

Atmosphere, 2023
Chinese loess provides the most detailed terrestrial records of paleoclimate changes. We employed the grain-size components of aeolian sediments to reconstruct the history of the East Asian winter monsoon (EAWM) on the Chinese Loess Plateau (CLP).
