Generally, extra fine metal wire is used in various modes depending on its uses: by twisting a plural number of pieces together, by weaving, in the state of single wire, by cutting in short pieces, etc. 316L extra fine stainless steel wires are used in producing electronic display screens, metal materials, materials for food industry and pharmaceutical industry, and also for high quality mesh filter owing to their advantages such as corrosion resistance and clean, etc.
It was observed that the original austenite grain was elongated and destroyed with the increase of the compression.
Fibrous structure was transformed into equiaxial grain after bright annealing of the three extra fine stainless steel wires.
On the contrary, coarse grains and zonal inclusion were influenced the subsequent drawing more or less with a material of TISCO.

WS steel has heterogeneous microstructural characteristic, consisting of equiaxed ferrite grains and massive pearlite at grain boundaries (as seen in Fig.1c).
The flaky corrosion products on the surface of WS steel intersected each other forming quite a number of extremely small holes (Fig. 4c).
Higher carbon content and traditional hot rolling processing (high rolling temperature and slow cooling rate) produce agglomerated pearlite and coarser ferrite grains in WS steel.

1.Introduction
Transparent conducting oxide (TCO) films are prerequisites for most photovoltaic applications and flat panel displays (FPDs) which have been subjected to a large number of investigations for decades [1].
Based on Kluth’s model [12], the films deposited at Ts=85oC belonged to the type A morphology (Zone 1) whose grains predominantly comprised oriented c-axis parallel to the substrate normal.
As Ts increased, the surface structure had shifted to the more compact type B and C morphology (Zone 2) whose grains, although still with a c-axis preferential orientation, exhibited a small inclination with respect to the substrate normal [8].
This process might induce major grain growth and, consequently, result in more compact structures with less surface roughness.

It should be noted that the number of pores located closed to the WC particles was higher than that observed in others area.
The dark phase was gathered at edge of WC particles and the shape seemed round and grain boundary was clearly visible, see Fig.4 (b).
In the same time, the microstructure of A11 after adding WC, it was found the amount of dark phase was higher, the dark phase was gathered at edge of WC particles and the shape seemed round and grain boundary was clearly visible more than non-WC coating.

The total number of scans was 20 with a spectral resolution
of 4 cm−1, a range of 400-4000 cm-1 and Happ-Henzel correction were used.
Chalcopyrite oxidation in both culture, with different grain size, were accompanied by a relatively low redox potential in the beginning of the test, then present a increment and finally small decrease with the time.
Copper extraction was around 50% for grain size 200 Tyler mesh while, grain size 325 Tyler mesh was around 40% and less than 6% Cu was solubilized in the chemical controls Fig. 1D.

It is found that the coating is composed of a lot of crystal grains in the shape of accumulating cells with different sizes, in which the distribution of the accumulating cells is in a well-proportioned state.
Because the micro-structure of the Ni-W alloy posses super fine crystal grains, which means that the grain boundary in the coatings per unit is increases, so the fatigue micro-cracks are not easily developed and result in large resistance for the micro-cracks to propagate.
In friction process, the number of micro-cavities may increase with the plastic deformation of the Ni-W alloy coating and they can connect each other to generate micro-cracks.

The experiment studied the relation of heating time with the nanocrystalline yield and grain size, as shown in figure 5.
Therefore, the crystal size and number of the first batch of germination of nucleus become the important factors to decide the final particle size[12].
In addition, the organic solvent diamine is strong polar substance with strong ability of absorbing microwave radiation, so the entire system can quickly heat up to the required reaction temperature, thereby obtaining a uniform grain.

Owing to the low crystallinity (nanometer-sized grains) and the poor adhesion to the substrate, cBN films have been far from application to various protective coatings.
The introduction of the chemistry of fluorine into plasma jet-enhanced CVD has enabled one to deposit high-quality cBN films with high-crystallinity (micrometer-sized grains) and good adhesion to the substrate [3,4].
The resulting film consisted of micrometer-sized grains with a crystallographic morphology and an in-depth cBN content up to 70 vol.% [6].
The film surface consists of a number of micron-sized cBN islands consisting of subgrains smaller than a few hundreds of nanometer.
