In recent years a number of reports on color film phosphating process[1-5] which overcame the deficiency in the traditional phosphating, but they also had some shortcomings, such as they used the expensive Molybdate, there treatment costs was higher than traditional zinc phosphating, and the resistance and adhesion of phosphate film corrosion were poor.
Meanwhile, long-chain polymer crystal structure also played a role in the crystal mediation agent, and made the crystal film of very small, dense spherical to instead of the traditional grain large, needle-like crystal film.

Their decomposition temperature was reduced with a number of their 3d-electron.
The metal grains grew rapidly with the annealing temperature as represented in Fig. 3.

The titaniferous blast furnace slag contains a large number of SiO2, Al2O3, CaO, MgO and TiO2.
Fig. 3 shows that TiO2 crystal grains appeared at 800 °C and the crystal phases were rutile and CaTiSiO5.

Among large number of electrical conduction material, carbon and steel fiber owns good strength and electrical function and electrical and heat function[1-5].
The coarse aggregate chooses pebble with grain size between 5-9mm.

Table 1 The process parameters of electron beam surfi-sculpt Accelerating Voltage (kV) Beam Current (mA) Focus current (mA) Swipe speed (mm/s) Swipe length (mm) Number of swipe repeats(swipe/s) 150 2.5 342 100 4 500 Results and Discussions Macrostructure Single protrusion up to about 1.5mm in height was produced with the correct combination of parameters,as is shown from Fig.3.
The formation of the needle grains is due to the fast cooling rate during electron beam surfi-sculpt process.

Recently, we have developed a number of methods of so-called non-isothermal kinetics (NIK) and designed instruments allowing one to obtain information about reactions of ceramic systems in a wide range of practically important temperatures and rates.
A theory based on ideas about thermally super-activated solid phase reaction diffusion as a limiting stage of gasless SHS could not explain a number of important phenomena.
These research method and devise offer great opportunities for solution of the following important tasks in civil and military industrial sectors: production of fully melted refractory substances (e.g. large-grain TiC used as a highly efficient abrasive), SHS in systems in which ordinary SHS can hardly be accomplished due to their low heat release (Si + C à SiC, etc), SHS-welding of dissimilar, refractory and ceramic materials and SHS of FGMs [2].
Experiments on ETE are performed by using samples 3–5 mm in diameter and 8–15 mm in height pressed from EM powders or rolled from a number of thin films and foils and characterized by high electric conductivity.
The numbers of 16 autonomous electron-optic channels are indicated on the X-axis.

All profiles (AR=0.571) are tested in a wind tunnel at air speed of 10 m/s at Reynolds number 6.5 x 105.
These four airfoil shapes will be studied at Reynolds number Re = 6.5x105 across a range of -4.5° < α < 20°.
The specimens were eroded by sand grains of the dune (from the same semi-arid step area and the average diameter of which is 80 µm).

The further discussion concluded that for a brittle material grain of meso-scale size, the theory of Maximum Tensile Strain is reasonable in explaining the strength, as for a brittle material sample of a macro-scale size, the mohr-columb theory is reasonable for its strength owing to the two important factors of cohesive strength and friction factorwere introduced. 1 Introduction In teaching Material Mechanics, one of the most important instructional objectives is to get a knowledge of mechanics properties of materials.
So first of all, we need to define heterogeneous meso-structures in the sample, which is by producing random numbers obeying Weibull distribution and filling them to the meso elements.
The Fig. 6 records the stress-strain curve and number of fractured elements at each loading steps, these could be considered as the number of acoustic emissions.
N6 N14 N23 N35 Fig.5 The damage pattern of at loading step 6,14,23,35 Fig.6 Stress-strain curve and number (N) of fractured elements at each loading step 5 Conclusion and Discussion In the paper, by means of numeric simulation, we revealed phenomena of multi-scale mechanics of brittle materials.

A number of biodegradable aliphatic polyesters have been developed and some of them are now commercially available because of their good biodegradability.
The probable reason was that a large portion of noncrystallizable units (MD) might be trapped in the crystal lattice as an impurity; when the content of the noncrystallizable units was increased, the crystallizable link of the chains became shorter, and thus the perfect spherulites changed to grain.

A number of laboratory studies have indicated that Ni-based alloy have significant potential in wear critical applications[6-7].
The difference between the hardness of the two alloys could be due to the fact that hard phases and smaller grains of the alloy with the addition of rare earth.
