The incorporation of multi-principal elements in alloys has always not been considered because of the anticipated formation of complex microstructures composed of multiple-phase intermetallic compounds or ordered phases.
In this paper, we aimed to prepare HEAs with high melting point as well as excellent ductility.

Introduction
Magnesium alloys find great potential applications in structural materials due to their high specific strength and excellent damping properties [1-3].
The previous studies demonstrated that magnesium alloys might undergo dynamic recrystallization (DRX) during hot working process, which significantly affected the grain refinement and improvement of ductility [5-9].
The present work aimed to investigate the co-effect of deformation temperature and strain rate on mechanical behavior and dynamic recrystallization of rolled AZ31B magnesium alloy thin sheet.

This leads to
alloy electrical properties, such as conductivity, which are comparable to those of the end
compounds.
In contrast, the very different atomic masses of Si and Ge represent a very large perturbation to the vibrational structure, and the thermal conductivity of the alloy is substantially lower than that of the end compounds.
These compounds enable the fabrication of materials with specifically engineered properties-including strain state, morphology, defect microstructure, selectivity of growth-as well synthesis of new and metastable systems that cannot be achieved by conventional Fig. 1 (left panel) Band gaps of group-IV alloys and III-V alloys relevant for IV/IV / III-V triplejunction solar cells.
Future research in this area will aim to establish the thermoelectricity credentials of SiGeSn alloys by systematically studying their thermal conductivity and Seebeck coefficients as a function of their composition and by carrying out ab-initio simulations of these quantities in alloys as well as in superlattices.

It was pointed that the filler content can be increased significantly without decreasing the processability by using low melting point metal alloys because these alloys are in liquid phase under processing conditions.
In our work the aim was to prepare an injection moldable composite material with thermoplastic polymer matrix and low melting point alloy filler.
Thermal conductivity of the PP/Sn-Pb compound as a function of the alloy content According to the standard, the melt flow rate of the composite material was determined at 0, 30 and 48 wt% Sn-Pb content.
Melt flow rate of the PP/Sn-Pb compound as a function of the alloy content Summary In this experiment the thermal conductivity of polypropylene was increased using Sn60Pb40 low-melting point solder.

The possibility of obtaining welded joints of large thickness parts using EBW with the evaluation of mechanical properties is shown, as well as dissimilar compounds of steel and composite on the basis of tungsten and bronze.
The optimal modes of electron beam treatment are picked up and the microstructure of the obtained compounds is investigated confirming their quality.
At the same time when welding these materials, there are no serious obstacles to the liquid phase connection caused by the formation of brittle intermetallic compounds [4, 5].
A known problem in welding of copper and copper-based alloys with steel is the penetration of liquid copper into steel leading to cracking.

The aim of presented work was
research of effect of TiN coating obtained by the RF-PCVD method on tribological and corrosion
properties of Ti6Al4V alloy.
However, titanium and titanium alloys have low wear and abrasion resistance.
The use of titanium alloys as bearing surfaces in total human replacements was widespread during the 1970s.
Particles of titanium and its compounds played a part of cathode.

The aim of the present paper is to study the mechanical characteristics of
alloys consisting of directionally aligned dendrites in the Ni3Al matrix using a directional
solidification method.
Optical micrographs of the cross sections of the alloys grown at the rate of 10µm/s.
In 23, 26 and 27 Al alloys, the dendrites formed more than the γ´ matrix, whilst for the directionally grown polycrystal in 24.5 and 25 Al alloys, the γ´ phase was dominant or the structure was entirely.
Conclusions Uniformly distributed dendritic fibers in γ matrix were obtained in (23-27) Al-Ni alloys by directional solidification.

The use of zinc-nickel master alloys is well studied and has a significant disadvantage - the significant wastage of nickel in the bottom dross.
All of these studies were carried out using Zn-Ni alloys Technigalva.
According to Technigalva technology, the Zn-Ni ligature contains nickel in the form of NiZn8 compound, the melting point of which is higher than the usual temperature in the bath.
