To establish the solid-state recycling technology of remarkably inflammable magnesium alloys. Bulk Mechanical Alloying (BMA) process based on the cyclic plastic deformation has been applied to demonstration experiment. Even starting from large machined chips of AZ91D alloys as starting materials, microstructures of original AZ91D can be refined in the solid state via BMA. Much lower energy consumption is necessary for this solid state recycling compared to the conventional casting process. BMA is one of the suitable recycling technologies to be morphology-free from starting materials.
