Mechanical properties of AZ31 Mg alloy produced from machined chips by the solid-state recycle method were compared to those of the reference alloy which was produced from an as-received AZ31 Mg alloy block under the same conditions with the recycled alloy. Tensile properties of the recycled alloy were comparable to those of the reference alloy, however, the recycled alloy exhibited poorer fatigue resistance than the reference alloy.
