In this paper, change regulation of hardness of target around crater by Wf/Zr-based amorphous matrix composite projectile and its mechanism are studied after firing test, and it is found that the section can be divided into 3 layers: the Martensite layer, the deformed fine grain layer and the normal matrix from the crater surface to the interior of the steel target and that the thickness of Martensite layer increases first and then decreases in the penetration direction when the velocity of projectile is 1200m/s.
The SEM image shows in Fig.4, and numbers in box stands for the hardness of test points.
It is shown that the section can be divided into 3 layers: the Martensite layer, the deformed fine grain layer and the normal matrix from the crater surface to the interior of the steel target by observing Fig.3 and Fig.5.
Conclusions (1) In the firing test, Martensite transformation occurs in target around crater, the hardness of target around crater distributes between HV700 and HV350, and it is found that the section can be divided into 3 layers: the Martensite layer, the deformed fine grain layer and the normal matrix from the crater surface to the interior of the steel target

Assessment is conducted by bottom-up, coarse-grained assessment make the global correction based on the results of the fine-grained, we select more indicators to deepen the coarse-grained assessment.
The combination of short-term and long-term can descripe the network in various aspects and provide decision support. 3 Hierarchical Network Security Situation Awareness Model Based on the Time Dimension The network system contains a large number of host nodes such as network equipments, safety equipments, these devices bear the task of monitoring the network and host operating conditions, they can describe current status of the network from different angles.
Each sensor has the inherent limitations to produce leaking and false alarms[7], the task of data fusion is synthesize and refine the data from different sensors to draw higher precision and less number of alarm data.
The first step of impact value decomposition is to find the TID in the ultra-alarm, with this TID, we can find the corresponding data like , Level is the intensity of the threat, Flaw is the loophole serial number of attack using, CT is confidentiality, AT is availability, IT is the integrity, and CoT is the controllability.

The array was in effect a very fine-grained replica of the original spatial arrangement of squares.
Testing showed that the arrays used were sufficiently fine-grained to avoid coarse-graining effects.
The diffusivities were scaled directly to the jump frequencies from site-to-site within each phase, time was scaled to the number of jump attempts of a particle.
The diffusivity was determined directly from the Einstein Equation (in 2D): D = /4t (6) where R is the displacement of a particle after a long time t and the Dirac brackets indicate an average over a large number of particle histories, in this case we used 105.
The number of jump attempts was set at 10 6: testing showed that this was adequate to obtain long time limit diffusion behaviour.

A number of works based on TEM observations have been carried out to characterize the dislocation behavior of �-CuZn alloy, and it has been found that the temperature of the yield stress peak approximately coincides with that of the transition from the dislocations of <111> at low temperature to the perfect <100> dislocations at temperature above Tp [1].
The plates were, then, annealed at 550 � for 10 hours and air-cooled to room temperature, resulting in the large grain size microstructures (Dave � 3~4 mm), which could minimize the effect of grain boundaries during the � Corresponding author : keeahn@rist.re.kr Title of Publication (to be inserted by the publisher) deformation.

In the tensile studies of laminated composites of Ni (ultrafine-grained)/Cu (coarse-grained) with a thickness ratio of 20:1, it is reported that there is a good relation between strength and ductility [1].
As shown in Fig. 1, model is constructed of the two single crystalline Al grains having a width 6.67 nm each in y-axis and one in middle of MG having a width 6.66 nm.
The total numbers of atoms in the simulation box are ~538538 atoms.
During simulation NVT ensemble (where N is the number of atoms; V is the volume; T is the temperature of the simulation box are fixed) is used.
As the indentation depth increases more number of dislocations emit and interact with each other (Fig. 4d).

Weight change/surface area Vs number of cycles graph has been plotted in Fig 1(a), which shows that Superco 605 following the parabolic behavior till 45 cycles only, after that weight become constant till 100 cycle.
Values of parabolic rate constants kp Fig.1 (a) (Weight gain/area) vs. number of cycles and (b) (Weight gain/area)2 vs. number of cycles plot for oxidised sample in air and salt at 900˚C FESEM/EDAX FESEM micrographs along with EDAX analysis at some selected sites for Superco 605 subjected to oxidation and hot corrosion after 100 cycles at 900°C are shown in Fig.2 (a) and (b) respectively.
The grain boundaries consist of higher amount of mangnesium which means mangnisum has been come out from grain boundaries and Mg have more diffusion towards grain boundaries while in fig 2 (b), it was observed that after hot corrosion porous and fragile oxide was formed.

Therefore, the use of TBBFS instead of pure titanium dioxide as photocatalyst material, can not only take full advantages of our solid waste and minerals resources, but also reduce the costs of photocatalytic material and find another way of rational utilization for a large number of China's accumulation of TBBFS[2，3].
Experimental material TBBFS: produced by Panzhihua Iron and Steel Company Group, TBBFS with an average diameter of between 1-10 cm, the internal distribution of a large number of pores, with high activity.
The study [7] view: The system can join a new phase ZrTiO4, while the ZrTiO4 is a limited solid solution, its structure is quite different from TiO2, ZrO2, the formation of new phase needs a special relative transformation process, therefore, under the 600 °C the new phase is in the nuclear and chemical ZrTiO4 period, and it can not form a complete grain.
However, the analysis of XRD and SEM (Figure 10, 11) shows that no new phase formation indicts the highly dispersed TiO2 doping substances into the matrix, and have the influence on grain refinement [8].
The introduction of Zr4 + inhibited the growth of TiO2 grains, so that for the process of slowing crystallization TiO2.

After heat treatment, the material showed an average grain size of about 25 µm.
After failure, an opto-digital microscope DSX500 from OLYMPUS was used to document the crack number and size observed in the gage length.
The limited number of the HCF tests (three) performed for each condition and the corresponding dispersions are likely to affect the Adj.R2 negatively.
These short cracks appear in few favorably orientated grains, and when their length reaches about 200 microns, which corresponds to approximately 8 grains, they propagate in the normal direction from the loading direction, i.e. as they become long cracks (Fig. 4.a).
This seems to increase the number of fatigue crack initiation sites and cracks confined in between high peak regions.

the normal loads 0.5 N and 2 N and the number of cycles 18000, 36000 and 72000.
The grain size of DLC and MCD coatings is about 1-2 µm and 0.5-1.5 µm, respectively.

COF versus number of cycles recorded on the DLC and MCD coatings.
The wear of diamond grains located close to the center of the crater is negligible, however a concave shape of the line scan could suggest that there is the wear of MCD coating.

There are large number of holes, cut into these ‘C’ sections and these holes act as joineries and points of attachments for various sub systems of the truck.
The sub-surface microstructure of the punched hole (fig.3d) shows deformed grain size up to a depth of 0.7mm from the hole edge.
In drilled hole sections, the grains close to hole edge were heated and elongated in hoop direction more than the bulk material of work piece.
Residual stress measurements from number of hole cutting operations show a tendency of hoop direction stresses to be more tensile than axial direction stresses.
