Meeting the needs of modern engineering requires improving the functional and operational properties of special alloys, including aluminum-based, given their widespread use. Due to the use of traditional methods such as doping, modification, heat treatment, etc. it is impossible to radically solve this issue. Modern high-strength aluminum alloys have a complex composition comprising several transition metal elements and the use of classical modifying additives for grinding cast grains of such alloys, does not always lead to the desired result due to the possibility of side chemical compounds of alloying elements with the modifier or offset point triple and more complex eutectics, the formation of which involves the precision composition of new high-strength alloys. Therefore, it is important to develop new methods of processing alloys, including using the action of a constant magnetic field on metal systems, in particular, aluminum-based during their stay in the liquid state, solidification and crystallization. Which requires the study of the relationships of the parameters of the superimposed magnetic field on the crystallization of the components of the microstructure of aluminum melts of binary and more complex compositions, depending on the concentration of intermetallic-forming alloying and modifying elements.
On the basis of the conducted researches it is possible to create new resource-saving technological processes of magnetic processing of aluminum melts aimed at forming the necessary microstructure of cast products without changing the composition of the precision alloy, as a result of improving their performance and saving cost modifiers.
