Sentence examples for mean grain sizes from inspiring English sources
We conducted laboratory dam-break experiments on initially fluidized granular flows using two different fine-grained powders (mean grain sizes 47 and 67 μm) down a smooth, horizontal channel with an impermeable base.
During high-pressure torsion, mean grain sizes rise from about 10 nm after mechanical alloying to about 20 nm.
Nanocrystalline (NC) metals (mean grain sizes d ≤ 100 nm) have enhanced mechanical strength as compared to coarse-grained metals (d ≥ 1 μm), and thus, are a promising alternative as structural materials for future high energy nuclear reactors.
The hot-rolled alloys exhibited refined grains (mean grain sizes ∼10 μm) and high densities of lattice defects (dislocations, stacking faults, etc)., both of which were obtained as a result of dynamic recrystallization during hot rolling.
Using resonant ultrasound spectroscopy (RUS), the room temperature Young's modulus, shear modulus, bulk modulus and Poisson's ratio were determined as a function of volume fraction porosity, P, for specimens densified by both hot pressing (HP) and pulsed electric current sintering (PECS) polycrystalline specimens, where P ranged from 0.030 to 0.233 and mean grain sizes ranged from 0.5 to 1.4 μm.
On the other hand, STM images of the films deposited by argon sputtering show mean grain sizes around 30 nm for a film growth rate of 0.05 nm s−1 and 70 nm for a film growth rate of 0.005 nm s−1.
From galvanostatic studies, it was shown that Pt mean grain size ranging from 11 to 15 nm was produced.
d and θ in the figure mean grain size and dihedral angle, respectively.
They concluded that sediments always become better sorted during transport, whereas the mean grain size and skewness vary with specific combination patterns (FB−: finer mean grain size, better sorting value, and greater negative skewness; or CB+: coarser mean grain size, better sorting value, and greater positive skewness).
The permeability structure due to mean grain size is then interpreted in the context of melt transport.
The permeability structure due to mean grain size may be approximated as a high permeability region beneath a low permeability region.
