In order to manufacture a thin film with outstanding properties, high purity, even grain size and high-density target material properties are required [3].
A number of recent studies have attempted to manufacture thermal-sensitive, brittle metal powder materials such as WC-Co and amorphous materials using the warm spray process [6].

It is known from previous studies that there are a large number of searches using the wet synthesis method to obtain calcium phosphate nanostructured powders.
These new features may contribute to biocements and biomaterials obtaining, with interconnected microporous nanostructures and microstructures, in which grain morphology and micropores favors wettability and capillary action.
The biphasic bioceramics are developed with interest of improving the grain morphology, microporosity, bioactivity and mechanical properties, which are not always achieved in bioceramics.

Introduction
In consideration of pyrotechnic composed by oxidant, combustible agent and adhesive is a self-contained oxygen system as oxidant providing oxygen required for combustion[1], it can produce a large number of high temperature gases and solid residues which have a certain sound effect through underwater continual and steady combustion.
Pyrotechnic which is composed by oxidant, combustible agent and adhesive is compressed into grains of which density is 1.8 g/cm3, diameter is 18 mm , weight is 5 g installed in the spray cavity and placed together with the resonant cavity which is located on the same axis with pyrotechnic charge nozzle.
Fig. 1 The diagram of test sample, including grain, spray and resonant cavity Experimental platform.

Technology Number Allocation: The technology number is allocated as per the following procedure:
1.
Then a Technology Number Allocation Register is consulted to find the numbers available for allocation in the technology group.
The allocated technology number and sheet number are also inscribed on the tape as illustrated in the figure much like would be the case with a book number on the spine of a book.

Multiple beams can be used to increase the number of filaments being formed, but the high
deposition rate would be sacrificed somewhat.
Coreless fibers with an elongated grain structure parallel to the fiber axis would be desirable for high temperature applications.
The beam-like character of a laser also makes it very amenable to the growth of CVD filaments with an elongated grain structure parallel to the filament axis.
Over 150 filaments were deposited in contrast with many other studies that only deposited a small number of filaments.
A number of filaments could be deposited along the edge of the index card which allowed a large number of total runs to be made.

The V(C,N) particles act as grain refiners.
When there is no nitrogen present (as in 3-a), less than 0.15 [wt%] C should be used to avoid graphitization at long exposures at 500 [oC], while heat treatment above 900 [oC] may lead to grain growth; with the addition of only 0.003 [wt%] N (as in 3-b), the two-phase field of austenite + V(C,N) is much extended, and grain growth can be avoided up to 1000 [oC].
The lines represent where a phase appears or disappears; numbers show on which side of the phase-boundary line that particular phase is stable.
The V(C,N) particles act as grain refiners.
Fig. 13 is an example on structure evolutions of dendritic formation (through competitive grain growth in a dendritic array) and eutectic growth [31-34].

Rare-earth elements substitute for
Sc in these precipitates, leading to a higher number density of smaller precipitates, which have
a greater lattice-parameter mismatch with Al than in the Al-Sc binary microalloy.
Also, a coarse-grained (≈1 mm grain diameter) structure forms after conventionally casting Al-Sc microalloys, within the maximum solid-solubility (0.23 at.% Sc at the eutectic temperature), and a high temperature homogenization within the singlephase α-Al region.
