冷轧作为储氢材料的活化工艺，在铸造镁合金中得到了应用。本工作研究的合金是AZ91D和三种实验的铸态和压铸态的抗蠕变镁合金(MRI153、AXJ530、ZAEX10430)。实验表明，AZ91D、MRI153和ZAEX10430具有比铸态纯镁更快的吸附/脱附动力学。另一方面，AXJ530的储氢性能最差。这些结果归因于铝和锌作为合金元素可能具有的有益作用。初生α-镁合金中的偏析可以解释铸态和压铸态合金储氢性能的差异。(C)2012爱思唯尔B.V.保留所有权利。
The effect of cold rolling, as an activation process of materials aimed to hydrogen storage application, was applied to some cast magnesium alloys. The alloys studied in this work are AZ91D and three experimental creep resistant magnesium alloys (MRI153, AXJ530, ZAEX10430) in the as-cast and die-cast states. Experiments showed that AZ91D, MRI153 and ZAEX10430 have faster absorption/desorption kinetic than as-cast pure magnesium. On the other hand, AXJ530 showed the worst hydrogen storage properties. These results were attributed to a possible beneficial effect of aluminum and zinc as alloying elements. Segregation inside primary alpha-Mg grains may explain the difference of hydrogen storage properties between as-cast and die-cast alloys. (C) 2012 Elsevier B.V. All rights reserved.
