“…It is known that nickel is an alloying element in some standard aluminum alloys, which are used to make parts of internal combustion engines [24,30,36]. In addition, in recent years, alloys of Al-Ni, Al-Ni-Fe, Al-Ni-Cr, Al-Ni-Fe-Ce, and some other compositions have received considerable attention from the standpoint of their use as heat-resistant and heat-resistant materials [37][38][39][40]. The casting properties of such alloys are quite high due to the eutectic of Al+Al 3 Ni.…”

This article considers the role of the main alloying elements that have the most significant impact on the formation of aluminum alloys physical and mechanical properties for operation at high temperatures. Significant interest in research and prospects of casting compositions based mainly on eutectic systems and elements or compounds that can positively affect the structure and phase composition of alloys to increase their high temperature strength is shown. The analysis and comparison of the

The influence of the internal and external pressure subjected to the tube from dispersion-hardened aluminium alloy was investigated. The approach which combines methods of crystal plasticity and mechanics of deformable solid was used to explore the limits of elastic and plastic resistance. The mathematical model of plastic deformation includes balance equations for deformation defects with regard to the generation and annihilation of shear dislocations, vacancy and interstitial prismatic dislocation loops, and dislocations in dipole configurations of vacancy and interstitial types and also equilibrium equation, geometrical and physical relations between the deformations, displacements and stresses. It has been established that as the temperature increases, the limits of the elastic and plastic resistance decrease. Results of investigation demonstrate that the hardening the alloy by nanoparticles significantly improves the strength characteristics of the material.

Abstract. The linear density and the concentration of point defects in heterophase alloy with nickel matrix and strengthening particles with superstructure L1 2 ( -phase) is obtained by methods of mathematical modeling. The influence of dispersion of the particles of -phase on the behavior of deformation defects is analyzed. The model includes mechanisms for braking the motion of dislocations in the cutting -phase, which are the cause of the anomalous behavior of the material with increasing temperature.
