This study aims to describe the preparation and characterization of SiO2/TiO2 core-shell particles.
In order to prepare the homogenous SiO2/TiO2 inorganic compounds by sol-gel process, SiO2 particles were used as the core, AcAc served as a chelating agent to chelate with TTIP (which was used as the precursor to TiO2), and PEG was added to stabilize the hydrolysis/condensation process.

Coating compound was examined by Bruker AXS X-ray diffractometer (XRD) using CuKα X-ray.
The coatings have almost same diffraction angles but difference in X-ray intensity, i.e. they consist of similar compounds with different quantity.

Investigation of Mechanical Properties in Ductile Iron with Alloyed and Unalloyed at Time and Temperature on Austempering
T.
The novel microstructure (ADI) outperforms several established, high-end ferrous and aluminium compounds in terms of capacity.
These characteristics are mostly influenced by the hotness treatment conditions and alloyed materials.
The current investigation aims to identify how the austempering process affects the spheroidal graphite iron's mechanical characteristics and to define the graphite's morphology at different austempering limits, such as austempering temperature and duration. 2.

Magnesium addition was performed by adding FeSiMg alloys.
Alloy iron with a carbon content of less than 2% is referred to as steel.
The composition of magnesium ranges from 3 to 12% by weight In Fe-Si-Mg alloys, and the required amount of nodularization alloy varies according to the type of process used and the type of alloy added, this amount varies from 0.9 to 2.5%.
Therefore, this study was conducted with the aim of investigating the effect of Magnesium content on the strength, stiffness and toughness of nodular cast iron. 2.

Traditional natural materials (metals, alloys and other structural materials) cannot often meet these high and conflicting requirements.
UHMWPE has high resistance to corrosive chemical compounds.
The aim of this paper is obtaining composite materials for structural use and investigation of their mechanical and dielectric characteristics.

The aim of this study was to evaluate the effect of Yb:YAG laser beam parameters on the microstructure and mechanical properties of the laser beam welded superalloys Hastelloy X to define a field of weldability.
Experimental procedure Alloy studied is the nickel-chromium-molybdenum alloy Hastelloy X which composition is given in Table 1.
To validate the weldability of these alloys, dimensions of cord section are measured and compared to standard specifications described in EN ISO 6947 (Fig.1).
Fusion zone shape and final solidification structure of these two alloys were evaluated as a function of laser parameters.

The present study aims to investigate foamed alloy deformation and examination of compressive response of aluminium foams created via a melt process similar to AlporasÒ route being realized with the usage of calcium carbonate CaCO3 as blowing agent by employing relatively ductile and high strength aluminium alloys.
The density of the parent alloys was of 2.7 g/cm3 and 2.8 g/cm3, respectively.
Not less than three samples of each solid alloys were tested under compression.

Studies in this area aimed at finding new protection solutions, compatible with the granular material in store.
Starting from the 7 metals of the Ancient World: gold, copper, silver, lead, tin, iron and mercury, science has progressed enormously, obtaining special alloys such as uranium or plutonium.
It is both physically and chemically unaffected by all solvents and chemicals used in industry, except melt alkali metals, fluorine and some halogenated compounds, at high temperature and high pressure.
The physicochemical processes that occur at the diffusion interface are complex, are physical and chemical, with the formation of complex chemical compounds in solid phase which can achieve a strong binding of the two materials of different chemical nature.
Thus for example in the case of diffusion welding of chromium-nickel alloys with ceramics based on silicon nitride, the chemical reactions that take place lead to the formation of chromium nitride - CrN in the interphase area, which provides a strong welding of a ceramic metal.
