SEM imagines exhibits that layered grains of the products become larger and tighter with increasing N2 pressures.
SHS technique has been effectively applied to produce a number of the MAX carbides, like Ti3SiC2 [12, 13], Ti3AlC2 [14, 15], Ti2AlC [16, 17], Ta2AlC [18], and Nb2AlC [19].
Typical layered grains of Ti2AlN can be seen in Fig.3.
With increasing N2 pressure, the layered grains of the products increase and become tighter.
The layered grains of the products become larger and tighter with increasing N2 pressures.

Fatigue crack initiation behavior For SUS304 and SUS304N, the fatigue cracks initiate in the grain boundary or in its neighborhood at approximately 10% of each total fatigue life.
Therefore, the fatigue limits in these materials depend on whether or not fatigue micro-cracks are initiated. 3.3 Micro-Vickers hardness and Transformation ratio Figure 4 shows the micro-Vickers hardness number of the grains with slip bands and without slip bands.
In the cases of SUS304 and SUS304N, the hardness number of grains with slip bands is approximately 15% higher than that of grains without slip bands.
On the other hand, in the case of YUS170, the hardness of grains with the slip bands are not higher than that without slip bands.
Changing in the micro-Vickers hardness number of the grains before/after fatigue test.

The composite zone became larger with the increase of axial force and number of passes.
It is concluded that FSP refined the grains in stir zone and increase in number of passes decreases the grain size to about 500 nm on the surface Nano composite layer, which in turn improves the tensile and yield strength of the surface composites.
The number of passes varies from one to four.
Grain are refined by FSP technique [14].
This can be achieved by grain refinement in solid state.

Wheat grains removed impurities are scanned by the Infratec 1241 grain quality analyzer of FOSS company, scanning wavelength from 850 nm to 1050 nm, 2 nm scanning step of.
The root mean square error (RMSEP) is the evaluation of parameter to choose the number of principal component, which depends on the effect of models selecting different number of components.
The number of nodes of hidden layer is eight.
The number of nodes of output layer is one.

It can be seen that as heating temperature increases, the grain size tends to coarsen.
When the heating temperature is 1100℃, the microstructure is still mainly based on granular bainite, but the grains begin to coarsen.
As heating temperature reaches 1150℃, the microstructure is still mainly granular bainite, but the grains are coarse and the austenite grain boundaries are clearly visible.
There are coarse M-A islands inside the austenite grains, as shown in Fig. 4f.
When cooling speed rises to 10℃/s, the number of granular bainite increases which presents irregular anisometric with vague grain boundaries, complete continuous boundaries are inaccessible and the grain size is uneven, and there are fine M-A islands distributing in or among grains (shown in Fig. 8b), which improves the strength and toughness.

The high number of pores was observed in CoCrAlY bond coat.
The elemental mapping of TBCs with ceramic layer produced from fine grain YSZ powder was characterized very varied layer thickness (Fig. 3 a, average 204 mm).
The elemental mapping of TBCs with ceramic layer produced from fine grain YSZ powder was characterized very varied layer thickness (Fig. 3 a, average 204 mm).
The overview of samples with TBC coating after deposition: a – YSZ; b – MSZ; c – fine grain YSZ; after isothermal oxidation test: d – YSZ; e – MSZ; f – fine-grain YSZ In the microstructure of TBC with YSZ ceramic coating the significant degradation after oxidation was observed (Fig. 5 a).
It is not possible to increase the operation temperature using fine grain YSZ or MSZ powders in comparison with conventional YSZ powder.

If the tempering time is too short, there may be cracks and grain quality can be affected.
Iguaz et al. [53] studied the effect of drying and tempering treatments on rice grains.The results showed that the proportion of cracked grains increases as both temperature and air evaporation capacity increase.It was found that the tempering period improved ricequality, reducing the number of fissured grains.
They authors presents the effect of the number of rest period in terms of energy savings.

Morphology observation showed that the grain size and grains boundary are decreased while the porosity was increased as the addition of LCMO increases.
The morphology observation showed that the grain size and grains boundary are decreased while the porosity was increased with the increases of La0.67Ca0.33MnO3 as shown in Fig. 4.
CONCLUSION The effect of addition LCMO in YBCO system increases the number of peaks, increasing the intensity of peak, and formed new peaks.
Grain size and grains boundary are decreased while the porosity is incresing as the x wt% addition of LCMO increases.

In the SEM image of 100 nm thick film, there are a large number of pits obviously, and the surface of the film is rough.
In SEM image of 400 nm thick film, the surface morphology shows that the grains again become more ununiform in size.
However, we also find that a number of obscure hexagon patterns distribution on the surface.
So the appearance of a number of hexagon patterns illustrate that the strain in the films further deceased and the quality of the film becomes better.
In SEM image of 500nm thick film, there are a large number of clear hexagon patterns on the surface of the film.

W-1% La2O3 (d) has grains of ~ 100 μm where La2O3 particles are homogeneously dispersed.
The Mo surface is mainly covered by grains of about 40 µm while some zones exhibit smaller grains of about 5 µm (e).
In the cross-section grains of ~ 5 µm are the dominant feature, few grains of larger size are present with elongated substructures.
On the contrary, an anisotropic structure with a number of interfaces much higher in a direction than in the perpendicular one (e.g.
The aspect ratio of the crater depends on heat propagation from the irradiated spot that on turn is affected by the number of phonon scattering points.
