Influence of Thermomechanical Processing Parameters on the Mechanical Properties of an Aluminum Alloy used in Cutting-Edge Technique

Abstract

Special aluminum alloys are mainly used in the aeronautical and machinebuilding industries, areas of technique where materials must possess superior mechanical properties. These properties are obtained as a result of special methods of elaboration and subsequent processing. The special properties of these alloys are also influenced by the alloying elements present in their chemical composition. In this paper it is studied the way in which the parameters of the thermomechanical treatment process applied to an aluminum alloy influence the mechanical properties of the studied alloys. Thermomechanical processing consists of solution hardening, cold plastic deformation and artificial ageing at different temperatures and various times of maintenance at these temperatures.
