In this study, Al matrix composites (AMCs) reinforced with few-layered MXene (FLM) were fabricated for the first time using self-assembly protocol and powder metallurgy. Individual FLM platelets, which decorated the grain boundaries without structural degradation, were singly incorporated into the Al matrix. The interfacial load transfer was considerably increased due to the generation of strong anchors at the FLM–Al interface via Al phase infiltration under densification. Consequently, the addition of 0.26 vol.% FLM considerably increased the composite strength by approximately 66%. This work demonstrated the effective application of MXene as a 2D reinforcement for AMCs towards high-specific-strength materials.

在这项研究中，首次使用自组装协议和粉末冶金技术制造了由多层MXene（FLM）增强的Al基复合材料（AMC）。将装饰晶界而不发生结构劣化的单个FLM血小板单独掺入Al基体中。由于在致密化作用下通过Al相的渗透，在FLM-Al界面处产生了牢固的锚，从而使界面载荷传递大大增加。因此，添加0.26体积％的FLM显着提高了复合材料强度约66％。这项工作证明了MXene作为AMC向高比强度材料的2D增强材料的有效应用。
