文摘：In this paper, the multi-layered LZ91/Al alloy composite materials were prepared by asynchronous accumulative roll bonding (AARB), and the effect of the multilayer structure on the electromagnetic shielding effectiveness of the alloy was investigated. The result show that the number of LZ91 and Al layers increase exponentially with the increase of AARB passes, and the LZ91 layer and Al layer, α-Mg phase and β-Li phase in the alloy are arranged alternately. Besides, as the aggregate thickness of the Al layer increases in the AARB process, the electrical conductivity of the alloy also increases. Thish can effectively improve the electromagnetic shielding effectiveness of the alloy.
