Service properties of aluminum-matrix precipitation-hardened composite materials and the prospects of their use on the modern structural material market

The methods of production, the structure, and the service properties of aluminum-matrix composite materials (CMs) hardened by high-strength high-module particles are discussed. Owing to high wear resistance, a low specific weight, and a low cost, such CMs are promising for application in many fields of machine building. The need for commercial development of these new functional reinforced CMs with hardening fillers of various natures and fraction compositions (including nanoparticles) as high-temperature and wear-resistant materials instead of traditional materials is grounded.
