In a number of cases, this allows to stop the engineering design and special purpose new materials application [1].
The intermediate grains size decreases from 19.6 mm at the initial condition to 4.5 mm after the electron beam irradiation at electrons beam energy density 20 J/sm2.
The steel surface fuses in the microcraters formation region, along the boundaries and in the grain boundary junction at electrons beam energy density 10 J/sm2 (50 ms, 3 impulses).

This is primarily due to the ultrafine-grained structure of the metal, which occurs during controlled rolling with accelerated cooling.
A number of publications [19-22] present the development of eddy current sensors with increased sensitivity.

Research on micro-arc oxidation coupled with electrophoretic deposition processing of HA/ TiO2 coating indicated that the number of HA particles integrated into the coating layer increased as the HA concentration increased [16] When plasma electrolytic oxidation was applied to ceria nanocomposite coating and ZrO2 nanoparticle on titanium substrate, it was reported that by increasing the concentration of nanoparticle the average size of surface roughness values was increased.
Chemical reactions are initiated next, and then nucleation and growth of the grains occur, resulting in the formation of dense particles.

The interest in nanomaterials is nowadays great as the transition from coarse-grained to
nanoscaled state leads to substantial changes in properties of the material.
The resulting material was a single-phase manganite powder with the crystal lattice of the orthorhombic modification and grains of 15-30 µm in size.
Note that the proportion of the specific surface area of powder particles measured by BET is close to this number (SN/SM = 5.9040 m2g -1 : 1.5722 m2g -1 = 3.75).

Fe-Ni based alloy powder was chosen as plasma cladding material, the grain size of which is 106-180 μm.
The oxide film hasn’t fall off during the isothermal oxidation which show that the heat stress is very little and grains of oxide bond well during the oxide growing.
For example, 1mol metal capacity is VM, the oxide capacity of 1mol metal generated is Vox, and the PBR is: (6) Among: M — oxide molecular weight; do — metal density; n — number of atom in oxide molecular; dox — oxide density; A — metal atomic weight.

The frist were white or lacte of grain calcites(cal-Ⅰ), with fine or short veins, developed bedding of the carbonatite, controlled by cleavage(Fig. 3A), Fromed in before the metallogenic period, irrelevated for mineralization.
The scond were white or grayish white of grain calcites(cal-Ⅱ), developed in orebody with cloddy and irregular, the calcites were dissolved and metasomated by lead and zinc (Fig. 3B), the calcites were observed that they cut each other under the microscope, and developed in the different stages of the same period, and formed later than lead and zinc (Fig. 3C).
A number of stable isotope datas form host rocks (δ13CPDB=-5.4 to 2.6‰, average was -1.8‰; δ13OSMOW=12.6‰ to 19. 4‰, average was 17‰; 87Sr/86Sr=0.711 to 0.731, average was 0.716) indicated the mineralization was closed to the basin brine relation [8]. δ13C and 87Sr/86Sr values of the first calcite were distributed close to host rocks and displayed similar charscters, they were higher than that of calcite in metallogenic period.

Therfore, such transitions are dominant in this case, and large number of Cd-based acceptor may exist
in the films due to the high vapor pressure of Cd.
On the other hand, it can be think that the defect levels which originate in grain boundaries may largely exist in the films prepared on the quartz glass substrate.
Of course, the crystallinity of the films is inferior largely in comparison with when it is prepared on the sapphire substrate, and it can also be thought that many grain boundaries exist in the films.
