Microstructure and mechanical properties of the annealed 6060 aluminium alloy processed by ECAP method
Journal Title: Archives of Materials Science and Engineering - Year 2016, Vol 80, Issue 1
Abstract
Purpose: The main goal of this paper is to present the investigation results of microstructuralevolution and mechanical properties changes in commercial EN AW 6060) aluminium alloyafter intensive plastic deformation, obtained by equal channel angular pressing (ECAP)techniques in an annealed state.Design/methodology/approach: Annealing heat treatment was used to remove varioustypes of internal stress in a commercially available alloy in order to increase workability of thematerial. The evolution of its properties and material behaviour was evaluated after 2,4,6,and8 passes of the ECAP process.Findings: It was found that the mechanical properties and microstructure during intensiveplastic deformation, such as that during the ECAP process, were changed. Plasticdeformation refined grains in the aluminium alloy and increased its mechanical properties.Research limitations/implications: The presented study shows results of theinvestigated material in an annealed state.Practical implications: The applied processing route allows development of materialscharacterized by high strength and ultrafine grain microstructure compared to un-deformedannealed aluminium alloy.Originality/value: The work presents data about the influence of intensive plasticdeformation on the microstructure and mechanical properties of 6060 aluminium alloy afterannealing.
