Table 1 Mineral composition of Several Alkalinity of the converter steel slag (%) Alkalinity C2S C3S RO CMS C2AS C3MS2 CaCO3 1.24 5~10 - 7~15 20~25 5~10 20~30 2.11 20~30 a little 15~20 - - - 5~10 3.07 5~10 35~45 15~20 - - - - 3 Problems of steel slag utilization The minerals of the steel slag are formed at high temperature (1600℃) for a long time, silicate minerals have plenty of time to form integrity crystal, which are coarse grains with high chemical stability.
If the steel slag powder is mixed up with slag powder, and the specific surface area of them is kept in the number of 450 m2/kg, when 20% ~ 30% steel slag is mixed in the compound powders, the activity of compound powders can reach or close to S95 level, which can meet the design requirements of the strength of concrete structure.

The PSi surface is a sponge-like structure, which consists of a large number of pores on the surface help the ZnO nanostructures to incorporate into the pores.
As we see in Fig. 1(d-e), the surface morphology of the PSi surface has pores that are filled with small particles with a uniform grain size.

In addition, surfactants can increase thermodynamics stability of cemented carbide powder, especially in ultra-fine grained cemented carbides ball milling procedure [5].
It plays role like intermediate, so the mixture powders are not easy crushed and it will help the compacts shape well. 3.4 Discussion of role of surfactants 3.4.1 Impact of surfactant on hardness It’s well known that hardness of cemented carbides is related to number of pores in alloy inside.

They pointed out that the water salinity and the sediment grain size were the critical influencing factors.
The total number of grid nodes is 277 in the x direction and 152 in the y direction (Fig.2), the minimum grid size is 300meter, and the maximum grid size is 3,500meter.

Introduction In recent years, the consumption of gasoline especially as an energy source is increasing rapidly due to the increasing number of population in the world.
Furthermore, it can be seen that the solid solution of the CexZr(1-x)O2 were homogeneous as well as the agglomerated small grain particles.

Earlier investigations showed that the shock-wave loading results in a sharp grain refinement (up to 30 μm) on the metal surface, and the segregation of carbon takes place [4].
The peculiarity of this type of treatment is the formation of a number of secondary microcracks, which testifies to the non-uniform stress-strain state within this section, which is connected with an increased density of dislocations and hardening of the material during treatment.

Fig. 3 (Left and Right) displays the 3D AFM images of thinner and thicker (0.95 to 7.45 µm) ZnO as grown layers respectively, where we can see that nanorods of height ~30 nm are vertically aligned but their grain size is increased due to diffusion process and eventually larger plateau like surface is developed.
Asghar is acknowlede the finciancial support of HEC under project number 624/R&D and technical support of UNC Chalotte, USA.

Boron nitride has a wide range of attractive properties, including high-temperature stability and strength, a low dielectric constant, large thermal conductivity, hardness and corrosion and oxidation resistance, leading to a number of potential applications as a structural or electronic material.
Compare with quartz fiber, although slightly larger dielectric constant and dielectric loss for BN fiber, it has higher thermostability, its crystalline grain will not grow up and strength will not drop even in an inert atmosphere at 2000°C.

In a number of fusible metals and alloys has been registered AE in the course of fusion and crystallization [3-5].
Numerical values of all AE parameters increased with increase in speed of cooling are less, and the quantity of grains is more.

Table.1 Chemical composition of Ti6Al4V titanium alloy Experiments and results Pure titanium and α+β -type titanium alloys, including the Ti-6Al-4V ELI and Ti-6Al-4V, were originally designed for use as general structural materials, especially for aerospace structures, and only later adopted for biomedical applications. [7] Titanium alloys, due to the hexagonal crystal structure, have a limited number of active slip systems and thus possess limited formability at room temperature [8].
This range has been selected because between room temperature and 650°C the regime is the conventional work hardening which is then increasingly counterbalanced by recovery with increasing temperature and between 750°C and SP deformation is active but influenced by dynamic recrystallization and dynamic grain growth, while at 800°C all parameters are optimal for superplasticity [10].
