INVESTIGATION OF THE CASTING PROCESS OF DEFORMABLE ALUMINUM ALLOYS OF THE Al-Cu-TiC SYSTEM WITH A HIGH SPECIFIC STRENGTH

Abstract

The analysis of the casting process and the mechanism of structure formation of deformable aluminum alloys of the Al-Cu-TiC system with high specific strength is carried out. The advantages and features of using the self-propagating high-temperature synthesis (SHS) for the purpose of creating nanostructured composite materials (CM) are considered. The results of experiments on the creation of CM of the Al+5%Cu+10%TiC system with a homogeneous structure are shown. TiC nanoparticles were introduced into the melt of matrix by using the SHS method with addition powders of titanium, carbon, and Na₂TiF₆ halogen salt. As a result, there is a sensitive increase in the strength characteristics of the obtained nanostructured composite materials with maintaining a high level of plasticity.
