摘要

在氩气保护下

采用机械球磨合金化法制备Mg-Al-Li合金材料

对合金材料的组织、吸放氢动力学以及热力学性能进行了表征。结果表明

机械球磨合金化法工艺虽然不能改变合金的相结构

但适当的机械球磨处理可以改善Mg-Al-Li合金材料的储氢性能。当球磨时间为60h时

合金材料的氢化量以及氢化/脱氢动力学与热力学性能均达到最佳。

Abstract

The Mg-Al-Li alloy hydrogen storage materials were synthesized by mechanical milling

and the mechanical milling effect on the hydrogen storage properties of Mg-Al-Li alloy were analyzed.The XRD analysis shows that although the mechanical milling can’t change the structure of Mg-Al-Li alloy

the appropriate time of mechanical milling can improve hydrogen storage properties.With mechanical milling of 60 h

the hydrogen absorption/desorption kinetic properties and thermodynamic performance for Mg-Al-Li alloy exhibit desirable.
