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 ...

Grain refinement strengthening mechanism of an austenitic stainless steel: critically analyze the impacts of grain interior and grain boundary

Journal of Materials Research and Technology, 2022
In order to probe the superior nano/micron scale mechanical behaviors of ultra-fine grain (UFG) austenitic stainless steel as compared with coarse grain (CG) counterpart, systematic nanoindentation tests were carried out together with post-mortem EBSD ...

Effects of GS3 and GL3.1 for Grain Size Editing by CRISPR/Cas9 in Rice

Rice Science, 2020
Grain size is one of key agronomic traits associated with grain yield and grain quality. Both major quantitative trait loci GS3 and GL3.1 play a predominant role in negative regulation of grain size. In this study, a CRISPR/Cas9-mediated multiplex genome

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.
