In the general case, P depends on the structure, degree of misorientation between the neighbouring grains, grain size, amount of liquid phase and its chemical composition [6].
The technology was introduced for manufacturing biological protection blocks made up of the joints subject to high requirements for heat resistance, corrosion and radiation resistance Based on the research, a new direction in compositional brazing was formulated, which consists in obtaining a composite structure in a weld exposed to dispersion in type II systems.
Conclusions 1) The mechanism and rate of the process is evaluated along with the driving force of liquid grain boundary propagation in type II systems that should not basically support this by thermodynamic criteria. 2) Mathematical planning of the experiment suggested that the long-term durability is ensured by the formation of a composite structure in the weld when W-3 Ni-2 Cu is brazed with solder 88.

However, there are certain difficulties because the ordered porous structure can collapse at the high temperature employed by the sintering process [2], and/or the addition of binders may lead to a deterioration in the adsorption/desorption properties.
Thus, it is meaningful to establish other methods for fixing the MPS onto substrates that do not degrade the unique porous structure and adsorption properties.
The obtained thick films of MPS possessed the same porous structure, and their water vapor adsorption properties were almost the same as that of the powder sample.
The thickness of the obtained MPS coating was about 100 µm, and its porous structure and adsorption properties were maintained after the EPD process.

In recent years many researchers have focused on bimetallic which shows apparently a higher photocatalytic activity than the single metal doped TiO2, because the second metal can change the electronic properties and the formation of active surface structures {Ou, 2008 #677}[3].
Crystalline Structures (XRD) and BET Surface Areas In the present work, the phase structure and the crystal size of the synthesized photocatalysts were determined by using XRD, (Bruker D8 Advance) with Cu Kα radiation 40 kV and 40 mA at 2θ angles from 20° to 80°, with a scan speed of 4°C/min.

The scaffolds containing CS were randomly presented the large sheet structure.
Similarly, scaffolds containing SF were randomly presented the fine fibrous structure.
The complete full round pore structures was randomly selected.
Therefore, the SF provided fine structure to the scaffolds while the CS provided large structure to the scaffolds.
The lowest biodegradability represented the stability of structure.

The as-synthesized products are composed of nanosheets with similar orthorhombic Aurivillius layered structures.

The recent research, regarding the cavitation resistance of the this alloy structure, shows a poor behavior of the semi-finished structure and somewhat improved by artificial aging volumetric heat treatment regimes.
It is known for its use, in the rolled state, in strength structures of aircraft, motorboats and in the field of high-speed rail [20, 34, 35], even vanes and structures of wind turbines [13, 12, 35-37].

The effect of voltage, tip-to-collector distance and calcining temperature on the morphology and crystal structure of nanofibres was investigated by scanning electron microscope (SEM), X-ray photoelectron spectra (XPS) and X-ray diffraction (XRD).
The surface chemistry of the SnO2/Al2O3 nanofibers was studied using the X-ray photoelectron spectroscopy (XPS) and the crystal structure was examined by XRD.

The residue crystallinity declined 74.34% from XRD analysis, the fiber structure was destroyed completely by acid hydrolysis from SEM photograph.
