Graphene/aluminum (Gr/Al) composites have attracted the attention of researchers all over the world due to their excellent properties. However, graphene agglomerates easily because of the van der Waals force between graphite sheets, thereby affecting the performance of the composites. Decreasing the agglomeration of graphene and dispersing it uniformly in the Al matrix is a key challenge. In the preparation process, predispersion treatment and deformation treatment can play important roles in graphene dispersion. Researchers have conducted a series of research and literature reviews of the graphene predispersion and consolidation of composites. However, they paid less attention to post-deformation processing. This review summarizes different deformation treatments involved in the preparation process of Gr/Al composites and the evolution of the microstructure during the process. Research on deformation parameters is expected to further improve the properties of Gr/Al composites and would provide a deep understanding of the strengthening effect of graphene.

石墨烯/铝（Gr / Al）复合材料以其优异的性能吸引了全世界研究人员的关注。然而，由于石墨片之间的范德华力，石墨烯容易团聚，从而影响复合材料的性能。减少石墨烯的团聚并将其均匀分散在Al基体中是一项关键挑战。在制备过程中，预分散处理和变形处理可以在石墨烯分散中发挥重要作用。研究人员对复合材料的石墨烯预分散和固结进行了一系列研究和文献综述。但是，他们较少关注变形后处理。这篇综述总结了Gr / Al复合材料制备过程中涉及的不同变形处理以及过程中微观结构的演变。变形参数的研究有望进一步改善Gr / Al复合材料的性能，并将提供对石墨烯增强作用的深刻理解。
