为建立极易燃镁合金的固态回收技术，采用基于循环塑性变形的块体机械合金化(BMA)工艺进行了示范试验。即使从大型加工的AZ91D镁合金切屑作为输入材料，也可以通过BMA在固态下细化原始AZ91D的组织。尤其是细小的金属间化合物Mg17Al12均匀分布于基体中。BMAed AZ91D具有比原始材料高三倍以上的高硬度。与传统的铸造工艺相比，这种固态回收所需的能源消耗要低得多。BMA是一种适用于无形态原料的固态回收技术。
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 magnesium alloys as input materials, microstructures of original AZ91D can be refined in the solid state via BMA. In particular, the fine intermetallics Mg17Al12 are distributed uniformly in the matrix. BMAed AZ91D shows high hardness more than threefold increase from the starting material. Much lower energy consumption is necessary for this solid state recycling compared to the conventional casting process. BMA is one of the suitable solid-state recycling technologies to be morphology-free from starting materials.
