| Abstract Scope |
There is an increasing demand to reduce CO2 emission to minimize global warming effect. To achieve this, a promising “solid-state recycling” process has been proposed for aluminum alloys to reduce energy consumption by directly extruding the aluminum scrap at high temperature. However, achieving a sound welding of the chips remains challenging, mostly due to an oxide layer at the prior chip boundaries, that further consumes Mg. Mg consumption could decrease the hardening ability through Mg2Si precipitation during subsequent thermal processing. Therefore, it is necessary to study the precipitation behavior in the chips-based extruded material to characterize the impact of Mg consumption during oxidation on the hardening capacity. In our work, we investigate the precipitation behavior and microstructure of chips-based extruded AA6060 alloy with different thermal processing. This work builds relationship between processing parameters, microstructure and properties, and can be used to deliver processing-specific guidelines for solid-state recycling on aluminum alloys. |
