Fig.6(a2) shows that the number of pits on the surface of Incoloy825, and there was a slight attack on the InconelG3.
Similarly, corrosion scale consisted of white grains as shown in Fig.7(b1), but the grains became fine relatively and local areas on the surface, Fig.7(b2) shows that the pitting was lightened.

Introduction A number of studies [1-5] have been dedicated to processes underlying the oxidation of sulfides of nonferrous metals.
In addition to the counter diffusion of ions of oxygen and the metals through a layer of oxide-sulfide products of the reactions, it was found that sulfur saturated the unreacted central part of the sulfide grains.
This is explained by the occurrence of diffusion processes and a different composition of the surface on the side of the sulfide grains.

The soil samples were air-dried at room temperature, and grounded at 0.074mm3 grain size.

Selenium in soil, grain, human hair and drinking water in relation to esophageal cancer in the Cixian area, Hebei Province, People’s Republic of China[J].

A number of empirical equations have been proposed to characterize densification behaviour and expose underlying densification mechanisms.
Using the Scherrer equation, the mean grain sizes of the TiH2 and SS316L phases in the powder blend were determined to be 10.5nm and 18.6nm, respectively.
This behaviour is uncharacteristic for conventional coarse-grained polycrystalline materials, but it has been observed and discussed for nanocomposite powders [21].

In a number of cases the specific microbial strains were secured from earthworms’ coprolites for effective protective bacterization of grain crops [5].

Introduction The stress and hardening behaviours of metals are related to structural features like dislocation densities or grain size.
The latter is related to the average intragranular misorientation gradient [13] through: ∑ ∆ == = 15 1 )F( x2bN. 1 1 θ θθ θ ρ dx d b (1) with F(θ) being the misorientation angle distribution calculated over the whole map in both x and y directions, b is the burgers vector, N is the total number of pixels and ∆x the step size.
The sum is limited to the range 1°<θ<15° to exclude most of the noise and eventual grain boundaries.

To determine an accurate estimate of GND density when analyzing polycrystalline materials, it is necessary to ignore the high angle grain boundaries from the calculation of GND.
White areas are regions of high excess dislocation density while black regions are grain boundaries or low confidence data.
Analysis on similar specimens but with a far larger number of section planes has yielded similar results.

The ZnO thin film showed diffraction contrast of the grains ca. 10 nm in size in contrast to quasiamorphous film with much finer grain size.
In view of probability, if the original ion clusters fall uniformly on the substrate and then rotate to the nearest ]1101[ direction, one can expect the number of crystallites coalesced to form )1101( thin films will be twice as much as those to form )0112( one.

The number of tests was 30 times, and to report the average value of the measured microhardness.
Adding appropriate content of CNTs can improve the degree of melting of powders, the internal defects of coatings reduces with the increasing melting flow ability of the powders, grain growth is suppressed by CNTs during crystallization.
Fewer defects and finer grains lead to higher microhardness of the coatings [14].

This limitation can be usually overcome by increasing the number of layers in coatings.
All coatings showed a densed and fine grained structure.
It had different grain sizes in the range of 80-110 nm, which showed that the growth of the island mechanism was dominated in the TiN layer.
