Strengthening and deformation mechanisms in nanolaminated graphene-Al composite micro-pillars affected by graphene in-plane sizes
Review articleOpen access
Abstract:

Highlights•Micro-compression tests were carried on graphene-Al pillars with various graphene in-plane sizes and laminate orientations.•The mechanical mechanisms of graphene-Al pillars were evaluated from loading-unloading cycles and microstructural analyses.•A 3 folds' reduction in the graphene size conferred an over 15% increase in the strength, and a different deformation mode.•The stronger isotropic and kinematic hardenings led to the higher strength of graphene-Al pillars.•The superior constraining effect of smaller graphene size led to the deformation kinking of graphene-Al pillars.
