Moreover, Leone aimed at pulse frequency, beam scanning speed, and current intensity [6].
Aluminum alloys have a number of desirable features, including low density, high strength-to-weight ratio, excellent casting capability, good machinability and damping characteristics, and they are now increasingly used in aerospace industry, automobile industry, mechanical engineering.
Therefore, we chose the aluminum alloy as experimental substrate material.
It can be a ternary compound when iron and silicon elements have enough contents.

Chip/Tool Interaction During Dry Machining of the TA6V Alloy M.
Although the actors agree on these advantages, its implementation remains delicate, in particular for aerospace titanium alloys (TiAl6V) with conventional tools.
Validation for carbide tools and titanium alloys In order to describe the material behaviour at high deformation rates, a new material model is used to take into account strain rate hardening, thermal-softening and strain-softening phenomena.
At 627°C, titanium and cobalt can also give the Ti2Co compound [11].

Zn(OH)2 phase was formed on the surface of anhydrous tricalcium silicate (C3S) main compound in cement.
ZnO has been known as a representative of the photocatalyst among semiconductors which has a direct band gap 3.3 eV at room temperature, due to their high photocatalytic activity, photocatalytic degradation of organic compounds and strongly resist microorganisms.
ZnO is considered as one of the most promising metal oxide semiconductor investigated extensively for photocatalytic degradation of organic compounds.
Therefore, the aim of this research is to investigate the effect of zinc oxide nanoparticles on phase composition and crystalline structure of cementitious materials.

Introduction Aluminum alloy has been used in the various fields as structural materials or functional materials because it has good specific strength, workability and corrosion resistance.
Grain refinement has been studied for further improvement of characterization of this alloy.
However, researching reported Hall-Petch plots of pure aluminum alloys, we found that there were many plots below the reported minimum grain size and positive deviation of the Hall–Petch strength in the size range [8-10].
The aims of this study are to reveal the chemical composition after working and the relationship between yield stress and grain sizes on materials with equal chemical composition.

Subject of the study is mathematical description of the course of hydrogen sorption processes by intermetallic compounds of the type TiMn1,5 when purified from gas impurities.
Recent studies show that to achieve ultra-high degrees of hydrogen purification, palladium metal membranes, palladium-silver alloys, ruthenium-iridium alloys, platinum-ruthenium, etc. should be used, despite the high cost and scarcity of their material [58,59,60,61].
Calculations were carried out for compounds of the structural type CaCu5 in the region of disordered a- and β-phases using the example of the LaNi5H2 system.

The SPS method makes it possible to use nanopowders (NP) as starting materials for the production of nanostructured alloys and ceramics.
Hydroxide compounds of Fe, Co, Ni were metallized by hydrogen for 1 h at temperatures of 400, 265 and 280°C.
It can be seen that the introduction of Co and Ni NP led to the formation of a less porous alloy.
The maximum bending strength of 313 MPa was observed for an alloy containing 0.5 wt. % Ni NP.
The increase in strength due to the addition of Ni can also be associated with the diffusion of Ni with Fe to form the corresponding dense Ni-Fe intermetallic compounds.

This study introduced magnetic field method, which changes long needlelike β-Al5FeSi phase to short needle-like even tiny blocks during the solidification process of alloy with the effect of magnetic field, aiming to decrease its frangibility.
Calculation on the pattern confirms that this phase is ternary compound,The molecular formula isα-Al8Si Fe2 .
