In addition Ti-Ni alloys are non-magnetic alloy.
As a result of its high corrosion resistance and the previous properties the Ti-Ni alloys has found a large area in medical applications [4, 5].The Ti–Co alloys are broadly used as implant alloys in dentistry and medicine for many years.
Topographical modifications of titanium and its alloys were aimed at increasing the roughness of implant surfaces, thus increasing the surface area of implants compared to larger smooth surfaces.
Upon successful immobilization of these compounds onto implant surfaces, the substrate is responsible for the load-bearing function of the implant whereas the coating should facilitate optimal integration into the surrounding tissues [11].

Introduction Due to the increasing cost of raw materials and especially copper alloys, mechanical and electrical industries found alternative products to replace copper.
In comparison, a raw CCA wire was also annealed in the same conditions at 400 °C to increase the growth velocity of the intermetallic compounds.

Apart from pretreatment, the phase composition of the final product contains intermetallic compounds TiAl, TiAl3, Ti3Al5, as well as the small amount of residual Ti.
Introduction The production of composite materials and alloys with special properties is one of the main tasks in modern materials science.
The formation of compounds in the solid phase practically does not occur due to the low contact quality of dissimilar powders and small values of solid-phase diffusion coefficients [4].

One of them is the use for modification of special steels and alloys.
One technique is alloys modification by small quantity of additives from insoluble particles of highmelting-point compounds, which initiate the process of crystallization.
The aim of this paper is to present the results obtained from the metallographic investigation on the microstructure and properties of the alloyed with nitrogen tool steel X210Cr12 after modification with nanodispersed Si3N4.

The biochemical compatibility of porous SHS-TiNi alloys is evidenced by numerous clinical trials [1-4].
The paper aims to study the structural features of the surface layers of porous TiNi alloys fabricated by self-propagating high-temperature synthesis using various modern techniques.
Porous SHS-TiNi alloys exhibit several advantages compared to porous TiNi alloys produced by other methods of powder metallurgy – diffusion or reaction sintering [5, 6].
As a result, the surface of the porous TiNi alloy is covered with a continuous layer of intermetallic compounds and condensed gasified impurities.

The aim of this work was to investigate whether the explosively welded metals are susceptible to hydrogen degradation.
Hydrogen embrittlement of the ferritic and austenitic alloys was often observed following cathodic charging [4].
B,C,E,F- melted zones Hydrogen deteriorates structures and reduces mechanical properties of stainless steels, alloys, and low alloy steels as well as the cladded materials.
After H-charging the corrosion resistance of the clad alloys was reversed.

The aim of the work is to improve the structure and properties of alloy discs D16, after HPT and aging, and after preliminary hardening with subsequent HPT and aging.
Thus, it can be assumed that the dispersed particles of isolated brittle intermetallic compounds Q(CuAl2), Cu9Al4, caused the multiple nucleation of cracks in the material of the alloy D16 when reaching the tensile strength 505 MPa и 729 MPa after AA and NA, respectively.

The composition and structure of the obtained alloys are investigated.
Tungsten was in the composition of an intermetallic compound, doped ferrite and a chemical compound of tungsten, and iron W6Fe7 in the alloy.
It was possible to observe other compounds, for example, tungsten carbides W2C, formed by reduction of tungsten from WO3 .
According to chemical and phase analyzes, it was found that the alloy of the obtained samples contains compounds of intermetallic compounds Fe7W6, Fe4ZrC and carbides W2C and WC, ZrC3, but the total proportion of carbides is insignificant due to the insignificant carbon content in the welding wire and slag.
