研究了具有不同累积轧制循环（ARB）的Mg/Cu超层压复合材料（SLC）的初始吸氢性能与微观结构之间的关系。在经过 5 和 10 个 ARB 循环的 Mg/Cu SLC 中，Mg 的氢化占主导地位，而在经过 20 和 30 个 ARB 循环的 Mg/Cu SLC 中，Mg2Cu 的氢化占主导地位。不同ARB循环的Mg/Cu SLCs的生长速率常数没有表现出显着差异。据认为，轧制 Mg/Cu SLC 中 Mg + Cu 层的平均厚度作为 ARB 循环的函数，对初始加氢性能和微观结构形成过程有很大影响。
The relationship between initial hydrogen absorption properties and microstructures of Mg/Cu super-laminate composites (SLCs) with different accumulative roll bonding (ARB) cycles was investigated. Hydrogenation of Mg was dominant in Mg/Cu SLCs with 5 and 10 cycles of ARB, whereas that of Mg2Cu was dominant in Mg/Cu SLCs with 20 and 30 cycles of ARB. The growth rate constants did not show a significant difference among Mg/Cu SLCs with different ARB cycles. It is considered that the average thickness of Mg + Cu layers in as-rolled Mg/Cu SLCs as a function of ARB cycles has a large influence on initial hydrogenation properties and microstructure formation processes.
