An HPT of 20-mm diameter specimens in as-cast state was carried out below constrained conditions, at space temperature, pressure P = six GPa, and quantity of turns N = five. It can be shown that the formation of nano- and submicrocrystalline structures and the refinement of eutectic particles in aluminum alloys simultaneously supply a a number of boost in strength when maintaining a high plasticity margin. This mixture of properties has been accomplished for the first time for severely deformed binary aluminum eutectics. The partnership involving the kind of eutectic particles, the structure formation approach and also the mechanical properties from the aluminum alloys has been established. The thermal stability of severely deformed aluminum alloys at heating up to 200 C has been studied. Key phrases: eutectic aluminum alloys; high-pressure torsion; microstructure; mechanical properties1. Introduction Presently, an urgent task will be the creation of high-tech aluminum alloys with elevated mechanical and particular physical properties, for example, a low temperature coefficient of linear expansion, increased wear resistance and/or elevated strength at elevated temperatures [1]. The widely utilized hypereutectic silumins (alloys on the Al i system) possess a variety of substantial disadvantages, namely, embrittlement, the require for modification in the course of melting, and decreased thermal PF-06873600 supplier conductivity. Developed in recent years, the m.
