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.

R=2.76×10-11AρZ8/9E5/3, where r is the SiC density (g/cm3); A is the atomic weight (g), and Z is the atomic number.
Thus, other proposed earlier alternative nucleation sites for the SFs such as low angle grain boundaries [8], and localized defects in the near surface region, attributed to clusters of impurities [9] should be explored in future work.

In this building, the traditional hollowing, the grain of ceramic and the brilliant red colour in Chinese traditional culture are blended in with the age's most advanced steel structure design in a perfect way.
Today, an increasing number of watch brands choose to expose the tuning part, the counterweight, and the balance wheel clearly.

For the JCPDS file number 01-086-074 and 00-003-0223 corresponds to calcite and cellulose phase, respectively.
The morphologies of the eggshells is seen that the ES-M samples have the porous scattered all over samples and the pattern like stack of lamella foliated and disoriented foliated grains.

A number of service benefits can be achieved in terms of mechanical, electrical and thermal properties and enable their applications not only in the initial military field, but also in aerospace, automotive, electric, chemical and transportation industries [2, 3].
The proposed strengthening mechanism of MMC-GNS composites are grain refinement, Orowan strengthening, load transfer from the matrix to GNSs and increased dislocation density [5].

Introduction Porous ceramic materials offer a number of useful properties including low density, high-temperature stability, permeability, high surface area, and thermal shock resistance [1-3].
When the sintering temperature is lower, the calcium ions can escape from the zirconia lattice and enter the boundary of zirconia grains, these ions can re-diffuse into zirconia lattice when more elevating sintering temperature.

The main reason why to make them exist is that, vacancies and oxygen atoms cannot sufficiently diffuse for lack of necessary driving force so that oxygen clusters cannot smoothly form and grow at lower temperature without a enough number of vacancies and oxygen atoms, (2) When temperature is 923K or 1073K, both amount and mean sizes of the oxygen clusters gained from the simulations are relatively reasonable.
Though temperature is over high, the strong diffusion only prompts the oxygen clusters formed preferentially to absorb more vacancy and oxygen atoms and to swallow the smaller oxygen clusters around them, like as “Ostward phenomenon” in grain growth, so that the amount of oxygen clusters decreases and their mean size increase, Conclusion A phase-field simulation is presented to study the effect of annealing temperature on oxygen clusters’ evolution in silicon wafer during low temperature annealing.

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.

This means the number of the rolling stages can be reduced down to a few times to get the plate to a thickness of 1mm.
Grains are SiCp,(b) eutectic Si of the as-cast strip, (c) microstructure of the ingot cast using the metal-mold.

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.
