Electronic properties of the perovskite structured materials strongly depend on the potential barrier and chemical composition state at the grain boundary.
For example, the remarkable electrical nonlinearity appears at random type boundaries, while the electrical properties of highly coherent boundaries are similar to those of the single crystals.
In this study, an analysis on the dislocation core and grain boundary structures have been intensively carried out with symmetric [001] tilt grain boundaries with 4° ~ 18°- tilt angles which gives the potentiality for understanding the relationship between the grain boundary characteristics and their properties [6].
The thin foils for electron-microscopy observation were prepared using a conventional method including a mechanical thinning to ~10 ㎛ and an ion beam milling to electron transparency at an acceleration voltage of 2 - 4 kV using Ar ion beam.
Therefore, it is conceivable that the change in a tilt angle affects the structure of dislocation cores because dislocation core itself has elastic force field and thus interaction of dislocation cores is more likely to become stronger in the higher tilt angle bicrystal.

Introduction In the early stage, the development of TMCs had been mainly focused on the defense system technologies such as aerospace engine and armor parts, thus their performance was a more crucial factor than the cost.
However, the cost problem cannot be overlooked any more, especially in the field of civil mechanical engineering.
Thus, the coating processes cannot ensure long-term protection as to shot sleeves, because they do not meet the requirements of adequate thickness, excellent bonding, suitable mechanical strength and toughness, and thermal shock resistance [2].
Finally, the filling and solidification of TMCs shot sleeve were simulated by the condition of material database and thermo-physical properties as given in Table 1.
The fluidity of molten TMCs can be affected by many variables such as super heating, mold temperature, pouring velocity and heat transfer coefficient between casting metal and mold.

This structure allows mechanical properties to be optimized.
This is due to produce the powders uneven loading, which directly affects the interface bonding and powder density.
This shows that the powders and the Al panel have a good mechanical bond in the same deformation conditions by pack rolling.

Polysulfone was chosen as a polymer because it has a strong structure at high temperatures, high mechanical properties and chemical resistance.
However, polysulfone membranes have hydrophobic properties [16, 32, 33].
%MMT has sufficient electrochemical, thermal, mechanical and electrical stability properties for use as a battery separator in lithium-ion batteries.

Study on the mechanism of magnetic paraffin control of crude oil based on the reorientation of paraffin crystals induced by magnetic field Zhang Weiwei1, a*, Wang Dandan2, b, Wang Tingting1 and Zhang Sanchuan1 1School of Mechanical Engineering, Zhengzhou University, Zhengzhou 450001, China 2School of Foreign Language, Zhengzhou University, Zhengzhou 450001, China adafeng360@aliyun.com, bbenedictiondd@126.com Keywords: crude oil; wax deposition; paraffin control; magnetic orientation Abstract.
The potential of MPC technology has attracted intensive researches on the structural and rheological properties of magnetized oil and the mechanism of magnetic treatment [2,3].
The nucleation of paraffin crystal may also be affected by the magnetic energy.
In the pipe transportation, wax-oil structures of low mechanical strength can be easily destroyed by the shearing action of oil flow, which could result in a decrease of gelation temperature [10,15].
