Development of high-strength domestic alloys and competitive technologies for obtaining multifunctional cast and composite products from them for the manufacture of special equipment, infrastructure restoration and import substitution in strategic industries.
popup.description2
The influence of centrifugal casting on the mechanical properties of aluminum alloys of different alloying systems: Al-Zn-Mg-Cu, Al-Cu-Si and Al-Mg, economically alloyed with PM and REM metals, was studied. Based on the results of the study of alloys of the Al-Mg system, economically alloyed with PM and REM, a new high-strength centrifugally cast alloy of this system was developed.
Data on the operating conditions of machines and mechanisms and requirements for the mechanical properties of structural materials for obtaining basic products for pipelines for liquid and gas media of medium and high pressure were systematized.
It was determined that the most optimal chemical composition corresponds to steel 22ХГ2САФ. Based on the thermodynamic and kinetic parameters of the phase redistribution of N and V in carbon, low-, medium- and high-alloy steels, it was established that in 22ХГ2САФ steel, both in the initial state and at carburizing temperatures, the amount of solid-soluble vanadium and nitrogen is comparable to their amount in 22ХГ2СФ steel, and the amount of vanadium nitrides is 4-5 times higher.
Scientific principles have been developed for the construction and production of cast reinforced frame structures made of iron-carbon alloys with high integrated physical, mechanical and operational properties obtained from gasifying models, which are achieved by connecting the external hardening matrix alloy with the internal metal frame through an intermediate layer saturated with pyrocarbon formed during its thermal contact with polystyrene foam of the model, which makes it possible to increase the integrated strength of such structures with a matrix of iron-carbon alloys by 1.5-2 times, and reduce the metal content by 1.3-2.0 times, and reduce the consumption of liquid alloy by 1.5-3 times compared to analogues of foundry products made by casting in sand molds and by gasifying models.
