METHODS AND PECULIARITIES OF OBTAINING ALUMINIUM-BASED HIGH-STRENGTH DEFORMED ALLOYS

Abstract

Methods and peculiarties of obtaining aluminum high-strength alloys are analyzed. It is shown that to ensure high properties, it is expedient to use not only alloying, but also the processes of reinforcement by metal fibers and cold rolling. As a result of studying the structural peculiarrties fiber-reinforced aluminum composition materials, it is revealed that the composite materials reinforced by steel fibers are of great interest as they have limited solubility in aluminium. A technology for obtaining composite alloys on the basis of aluminum which includes casting, rolling and heat treatment of composite materials with a steel grid is developed. After rolling and small pressing, the strength of the obtained aggregate, in case of durability of 3300-3600 MN/m² of steel wires, is equal to 1200... 1250 MN/m².
