Figure 5 depicts that large amount of inter dendritic Al-Mg2Al3 eutectic (gray) in the matrix of aluminum solid solution with grain boundary clearly defined and inter metallic component being visible.

Annealing treatment was found to induce changes in microstructure, surface roughness, grain size and so on, indicating that with the increase of annealing temperature, the amorphous state of GST materials change first to face-centered-cubic (fcc) phase state and finally to the stable hexagonal(hex) state.
For peak B, in the crystalline structure of the hex, because Sb atom is lighter than Te atom, Te atoms are replaced by Sb atoms more in (Te2) Sb-Sb (Te2), so peak B drift to higher wave number.
At the same time, Te atoms which were replaced by Sb atoms may replace other atoms which bonded to Ge to get more GeTe4, so peak A drift to lower wave number, because Te atom is heavier than Sb and Ge atom.

Composite cathodes (LSM + YSZ) increase the number of electrochemically active sites for oxygen reduction (three phase boundaries of electrolyte/cathode/air) [4].
Fig. 2 shows the cross-section of a cell in an SEM image and the orientation of the YSZ grains visualized under conditions of electron back scattering diffraction (EBSD).
In the present example the typically large cubic grains extent over the complete thickness of the thin anode supported electrolyte.

The number of acoustic emission events during cooling was always significantly larger than during heating.

Under the certain experiment condition, with the content of the abrasive 10% and grain size 800# of SiC, best machining effect can be achieved.
When the content of abrasive is low, there are little abrasive particles spreading around in the grinding fluid, so the number and the cutting capability of abrasive particles are limited.
It is mainly because the number and the cutting capability of abrasive are limited when the content of abrasive is low.
As the content of abrasive increases, the number and the cutting capability of the abrasive improve, and the surface of the workpiece becomes smooth.
Under a certain condition, with the further increase of the content of abrasive, the number of the abrasives which participate in the MR-effect grinding fluid reaches to saturation and keeps a balance level.

One of the factors is the number of loads, which is taken into account by introducing a separate multiplier as a function of the number of loads N.
The number of applications of repeated loads is 106 and more.
The limit number of loads n is usually n=100…200.

Large numbers of superplasticizers are absorbed onto the surface of C3A and C4AF.
If there were too much C3A and C4AF, large numbers of superplasticizers would be absorbed.
With reasonable increase in the maximum grain size, total surface area of aggregate decreases, so the workability of fresh concrete can be improved.
The dissolution rate of dehydrate gypsum is higher than that of anhydrite, so large numbers of sulfate ions can be generated during mixing.
One is to make superplasticizers into particles with different grain sizes and dissolution rates.

The process of 3DP was patented in 1994 by Sachs et al. under U.S. patent number 005340656 [1].
Currently only a few final products are produced by RP machines, but the number will increase as metals and other materials become more widely available [17].
It should be noted that in casting while solidification process is going on, there are preferred grain growth direction and grain re-orientation/ redistribution takes place [4, 22].
Fig.5), at 10mm shell wall thickness, mixed grain with uniform distribution have been observed, whereas at other shell wall thickness dendrite structures have been observed.
This may be because of better heat transfer rate conditions, which results into refine grain structure (with no dendrites).

Segregation of components is limited into the powder particles，which can eliminate the macroscopic segregation of conventional casting and has the advantages of uniform microstructure and fine grains，obtaining good yield strength and fatigue properties.
Engine fuel contains a large number of impurities such as S, Cl, Na, K, etc., these impurities can react with O or NaCl in the air (high content of NaCl over the coast or over the ocean) during combustion, and a mixed salt film such as Na2SO4 and NaCl is deposited on the surface of components, which is easy to cause hot corrosion of superalloy components.
Two different morphologies were observed on alloy surfaces, namely compact finer-grain crystalline and porous coarse-grain crystalline, as presented in Fig. 2.
The morphologies of The New alloy and FGH96 were observed on alloy surfaces, showing that more compact finer-grain crystalline film formed on the surface of The New alloy compared with FGH96.
A large number of mixed oxides formed in the external corrosion zone of FGH96, but no continuous oxides formed.

They look like grains of different dimensions in the range of not more than 100 µm.
Grains of dispersed humine have dimensions in the range of not more than 30 µm.
After dispergation the number of porous particles decreased.

Introduction In the deformed materials, the local plastic strain is very complicated and different form the macroscopic plastic strain, because materials are locally non-uniform due to the presence of microstructural features like grains, grain boundaries, particles, pores, void, cracks and so on.
Index numbers i and j specify individual pores.
The ratio of success tracking, η is calculated by the number of correct tracking divided by the number of all markers.
