Formability of AZ31 Alloys Prepared by Hot-Extrusion of their Machined Chips

Abstract:

Machined AZ31 alloy chips were consolidated by hot-pressing and then hot-extrusion at 300 °C, and their workability was evaluated. The consolidated sample has a fully dense microstructure with fine equiaxed grains. The　compression and backward extrusion tests reveal that the consolidated AZ31 chips have a good workability at above 200°C.　It is said that the recycled AZ31 alloy by hot-extrusion of the chips is suitable for forging materials and the process is useful for the recycling of Mg chips.
