Abstract

To date, the Republic of Kazakhstan has a high potential for the development of production, processing and production of finished products from aluminum alloys of local content, provided that the modernization of current production facilities is updated or a new group of aluminum alloys is created. To do this, there are all the necessary resources, namely: the availability of raw materials, fairly cheap electricity, rising metal prices.

One of the solutions to this problem is the use of modern technological solutions to create a group of aluminum alloys from domestic raw materials.

The main purpose of the article was the scientific substantiation of the chemical and phase compositions of thermally stable aluminum alloys with an increased content of impurities (primarily oxygen and nitrogen).

The methodology of scientific research is based on developments in the field of the study of phase equilibria and the construction of phase diagrams of multicomponent metal systems.

The article presents an analysis of the state diagram of the Al–Fe – Si system using the Thermo-Calc program: polythermal sections were constructed and analyzed in order to determine the concentration boundaries of the appearance of primary crystals of Fe-containing phases. Based on the calculation of the parameters of the primary crystallization of Fe and Al-containing phases, the possibility of evaluating the efficiency of alloying these alloys with elements such as carbon, oxygen, nitrogen is shown.

From a practical point of view, the complex of proposed studies will allow to scientifically substantiate and develop new technologies for the production and processing of semi-finished products and finished products from aluminum-based alloys and functional materials with a given structure.
