In the past, Fe-Al-Si alloys were thoroughly investigated in numerous studies especially from point of view of aluminium, because of the importance of the commercial Al-rich alloys containing Fe and Si as impurities.
The Al-Si system is also the basis for widely used commercial casting alloys the so called silumins.

In these industries aluminum alloys can be used to replace steel parts of carcasses (car body).
Chemical composition (%) of copper-zinc alloy, type CuZn37 Cu Ni Cu Fe Sn Al Others Zn 62-65 0.25 £1 £0.1 £0.1 0.05 £0.1 Balanced Alloy 4043 is one of the oldest and most widely used for filler metal brazing alloys.
The brazing time is approx. 1000 sec. at temperature 600°C and the thickness of intermetallic compounds denotes the extent of atomic diffusion [14].
The addition of 4043 alloy into the AA6016-T4 and CuZn37 braze alloys significantly improves its wettability on both brazing materials.

Conventional approaches to increasing strength properties of aluminum alloys based on modification of their chemistry by alloying (Cu, Mg, Zn, Si, Li, Ag), and on development of heat treatment and thermomechanical treatment methods are almost exhausted [2], while the use of expensive alloying elements, for example, zirconium or scandium, increases the production cost of such alloys.
Some papers [7-10] show by experiments that asymmetric rolling of aluminum and its alloys forms the UFG structure.
This paper aims at a numerical study and simulation of grain evolution and dislocation density during asymmetric cold rolling of aluminum alloy 7075 in an SPD mode.

The use of powder alloys in double sintering technology provides the material hardness and the strength increase.
Of scientific and practical interest is the use of nanopowders (TiN, Fe2O3,Y2O3, WC, TiC, SiC, VC, NbC, TiO2, Al2O3, MgO, ZrO2) to modify the structure of metals and their alloys with the aim of obtaining higher physical and mechanical properties of products [3,4,5,6,7,8].
The chemical composition of the studied alloys is given in table 1.

The aim of this work was to study the influence of TIG-welding on the structure and properties of welded joints of pseudo-β titanium alloy VT19.
Analysis of filler metal effect on the mechanical properties of the compounds, led to the conclusion that the low strength values in the state after welding have joints made without the filler wire (Table 2).
Welds of VT19 alloy obtained by TIG-welding without filler material, have values of ultimate tensile strength at σ0.2 = 860 MPa, for the decay of metastable phases and to ensure uniform strength compounds, they must be subjected to the following heat treatment - annealing.

Very small concentration of hydrogen in metals and alloys can lead to irreparable defects, such as flakes in carbon steel, pores in aluminum and copper alloys, ductility reduction of titanium alloys [4,5].
In this context, the aim of this work is to develop methods for investigation of hydrogen distribution from the surface to the depth in technically pure titanium alloy with the help of glow discharge optical emission spectroscopy.
