One of the two samples served as a reference and was made from the same Cu material, which was well annealed and coarse grained (grain size > 100 μ m ).
Fatigue growth behaviour of long cracks in an ultra-fine grained steel (grain size 1 μm) was investigated.
Ultrafine grained steel (grain size 2 3 µm) that has a numerous futuristic applications in automobile and engineering industry has been developed in laboratory scale with plain C Mn and C Mn Nb, C Mn V compositions.
The sandstone deposits are fine to coarse grained and generally, grain size increases in a northeasterly direction, i.e. towards the flanks of the basin.
In Portland, U.S.A., following the 1980 Mt. St. Helens eruption, sweepers were reported to be removing ~50% of fine-grained (median grain size ~31 microns; Shulters and Clifton 1981) tephra from roads.
It is shown that the deliberately adjusted formation of intermetallic particles beneficially influences dynamic recrystallization and grain growth, with the result of a fine-grained microstructure (grain size < 2 μm).
In this experiment, we tested the fine-grained size discrimination abilities of humans, other apes, and monkeys.
We here compared six primate species, including humans, chimpanzees, bonobos, gorillas (great apes), olive baboons, and long-tailed macaques (Old World monkeys) in a task on fine-grained size discrimination.
In sum, the gorillas were outperformed by the other species regarding these fine-grained size discrimination abilities, but there were no significant differences between the other apes, monkeys, and humans.
The room temperature mechanical behavior of free-standing, coarse-grained gold films (grain size greater than 1.5 μm) was investigated by uniaxial tensile testing.
Here we performed Fe ion irradiation to 150 dpa at 450 °C on bulk coarse-grained (CG, with a grain size of ∼2 μm) and ultrafine-grained (UFG, with grain size of ∼320 nm) T91 steels.
