The technology uses a liquid medium to replace the die or punch to deliver loader, in order to achieve pipe special shaped cross-section shape, which not only reduces the mold cost and shorten production preparation cycle; in the high pressure liquid acting, pipe only happen a non-cutting metal volume plastic transfer, significantly reducing the consumption of raw materials; in hydraulic forming, metal materials more dense grain structure, the metal flow line will not be cut off.
As the pipe length increases, the critical buckling instability pressure increasing, reducing the number of circumferential buckling wave; With the pipe thickness increasing, the critical buckling instability pressure increases, the number of circumferential buckling wave is also reduced; with a certain shape defected tube buckling instability pressure decreased significantly compared with the ideal pipe, but the basic shape will not affect the effect of forming parts.

Kiliç, The effect of the cutting direction, number of blades and grain size of the abrasives on surface roughness of Taurus cedar (Cedrus Libani A.

High technology content and high added value products such as high indium, ITO target and indium containing semiconductor materials have not been able to form the market competitiveness, and low production, require a large number of imports from abroad.
Therefore, developing the technology of ITO target is an existing target of choice for deep-processing technology and is also very urgent and necessary[3-4].ITO nano-powder is widely used for preparation of ITO film and ITO target, and it is very strict for powder used for the preparation of ITO target, such as high purity, fine grain size and uniform.
It can be seen from the figure that there are a lot of amorphous material at 200℃ because crystalline phase transformation and solid-doping reaction are not complete under the low calcination temperature, the product is uneven and the main color of powder is blue, the electrical conductivity is poor because the diffraction peak is not obvious which can not produce a large number of conductive carrier, The peaks began to appear while the calcination temperature was above 400 ℃, and the peak half-width tend to narrow, crystal structure became to more complete while the calcination temperature increased to 600 ℃, When the calcination temperature increased to 800 ℃, the peaks became very sharp, crystal crystallized completely, the particle size increased, dispersion was good, and the main bod y color was pale yellow compared to 600 ℃, Better crystalline powder can be achieved above 600 ℃ according to the above analysis.

It not only takes up a lot of farm, forest land, and with the increase of number of tailings, the amount of land area will continue to increase.At the same time, by the influence of factors such as technical level, beneficiation technology, equipment performance, economic capacity, operation method,inevitable some useful elements into the tailings.
The resource of tailings Along with the social economic development, a large number of mines undressed ore resources are declining and even exhausted.
A study indicates that tailings on the resource characteristics is similar with the traditional building materials, ceramics, glass raw or other basic material , actually it is processed into fine grained incomplete mixture, mix can be used in the production.

Material and Experiments The material investigated within the CRC 920 is a fine grained carbon bonded alumina (Al2O3-C).
This is equal for SPT as well as B3B because the stress at the central point is independent from the number of supporting points [2].
The number of specimens tested for each setup is 30.

Fig. 1: Experimental set up for high speed end milling of Silicon A micro-grain cemented carbide tool with plasma CVD coating (diameter = 2 mm, rake angle = 5º) was used to machine rectangular specimens of single crystal silicon (dimensions = 20 mm x 15 mm x 5 mm).

The Fatigue Fracture of the Characteristics and Reasons The fatigue fracture refers to the metal components or confined device in the far below materials tensile strength limit alternating load, after a certain number of circular function the cracking phenomena of what happened.
With metal components in alternating stress function, its own existence defects, especially on component surface stressing concentration areas, such as grain boundaries, processing daogen, corrosion pit, section upheaval, and so on.
Along with the increase of number of alternating stress, sliding belt broadens and stokes and appears slip with cracks in the phenomenon.

The thermocouple was made up of TC4 and constantan wire and hot junction was formed when the cutting action of CBN grains damaged the insulator layer around constantan wire.
Table 2 Configuration of cup wheel with internal cooling structure Diameter 80mm Abrasives CBN Grit 60 Segments number 26 Bonding agent Ceramics Comparison experiments of grinding temperature were conducted under almost same grinding parameters using novel wheel under different cooling methods to confirm its effect in reducing grinding temperatures.
As the grinding temperature was lower than 540℃, morphology of the surface was clear and smooth, and severe plastically deformed coating layers and a large number of micro-cracks were observed on the ground surface by SEM when temperature was higher than 750℃.

From then on, a number of researchers successfully synthesized Ti3AlC2 bulk materials by various methods [2-6].
According to the ref. [8-10], The MSR may be ignited after a certain activation time, as milling reduced the particle size, thoroughly mixed the components, and increased the number of chemically active defect sites.
One of the most salient microstructural characters is that the agglomerates are consisted of ultrafine grains.

Numbers of scientists have concentrated their efforts on the studies of line contact problems.
