▎ 摘　　要

Cyclic compression tests were conducted on 2.5-mu m-diameter nanolaminated graphene-aluminum (Al) composite pillars. The composite possessed three times higher damping coefficient than its pure Al counterpart, which was rationalized by the enhanced dislocation hindrance at the graphene/Al interfaces in the composites. Moreover, the cyclic compression of micro-pillars produced similar damping coefficients as the corresponding bulk sample, providing a novel and convenient approach to assess the cyclic deformation behavior and damping properties of structural materials.
