Two-dimensional graphene plateletes with unique mechanical, electrical and thermo-physical properties could attract more attention for their employed as reinforcements in the production of new metal matrix nanocomposites (MMNCs), due to superior characteristics, such as being lightweight, high strength and high performance. Over the last years, due to the rapid advances of nanotechnology, increasing demand for the development of advanced MMNCs for various applications, such as structural engineering and functional device applications, has been generated. The purpose of this work is to review recent research into the development in the powder-based production, property characterization and application of magnesium, aluminum, copper, nickel, titanium and iron matrix nanocomposites reinforced with graphene. These include a comparison between the properties of graphene and another well-known carbonaceous reinforcement (carbon nanotube), following by powder-based processing strategies of MMNCs above, their mechanical and tribological properties and their electrical and thermal conductivities. The effects of graphene distribution in the metal matrices and the types of interfacial bonding are also discussed. Fundamentals and the structure-property relationship of such novel nanocomposites have also been discussed and reported.
具有独特机械、电学和热物理性质的二维石墨烯片由于其轻质、高强度和高性能等优异特性，在新型金属基纳米复合材料（MMNCs）生产中作为增强体使用时可能会吸引更多关注。在过去几年中，由于纳米技术的迅速发展，对用于各种应用（如结构工程和功能器件应用）的先进MMNCs的开发需求不断增加。这项工作的目的是回顾最近关于用石墨烯增强的镁、铝、铜、镍、钛和铁基纳米复合材料在粉末基生产、性能表征和应用方面的研究进展。这些内容包括石墨烯与另一种著名的碳质增强体（碳纳米管）性能的比较，随后是上述MMNCs的粉末基加工策略、它们的机械和摩擦学性能以及它们的电导率和热导率。还讨论了石墨烯在金属基体中的分布影响以及界面结合类型。这类新型纳米复合材料的基本原理和结构-性能关系也已进行了讨论和报道。
