A variety of environmental and material design challenges coupled with component design concepts has given rise to a large number of coating deposition processes [1].
AlCl3 vapor reacted with the nickel and grains of intermetallic phase NiAl were formed according to the reaction: 2AlCl3 + 2Ni + 3H2=2AlNi + 6HCl.

According to those data presented in Figure 1, it is observed that the powder mesocarp babassu and microcrystalline cellulose showed similar grain size, once the highest percentage of particles passed through the tamis residual opening of 0.125 mm.
This result was expected because there is in the granulated an aggregation of a larger number of particles, which gives an increase in their diameters.
These results were obtained through the babassu granulated has a larger number of aggregate particles.

Among various synthesis routes, sol-gel based processes exhibit a number of advantages such as great flexibility, relatively low cost, simple preparation conditions, easy controllability [10].
When the calcination time was prolonged from 2 hours to 3 hours, the peak intensity was greatly increased because an increase in the calcination time makes grain growth and better crystallinity.

Ramadoss P. [1] conducted a review on considerable number of data that were collected from pervious published papers to study the correlation between compressive strength, flexural strength, and split tensile strength.
(4) Esquinas et. al [5] conducted and experimental study to investigate the effect of using fine grain wastes generated in asphalt plant on the properties of self-consolidated concrete.
A total number of 21 experimental data sets were collected from four studies which include the flexural tensile strength and splitting tensile strength of SCC.

Construction of groundwater reservoir, increasing the number of the reservoir water level fluctuation under mainland, causing the soil compression and rebound repeatedly, and producing the irreversible plastic deformation.
Porosity reduction rate with the variation of the number of cycles could reflect the impact of groundwater level lifting on the capacity of groundwater reservoir.
The microscopic mechanism of the above-mentioned law: the sand is granulated structure composed by a single grain structure which has little contact between particles.

Depending on optical microscopy and SEM examinations, it can be observed that as the cooling rate decreases, the number of coarse precipitates increase (Fig. 7 and Fig. 8).
Slow cooling results in a higher number of grain boundary precipitates and a wider precipitate free zone (PFZ) [9].
