Carbon nanotube (CNT) reinforced material composites have attracted considerable attention due to their outstanding properties. However, an understanding of reinforcing mechanisms, and how these mechanisms interact in a given material system, is still lacking. The potential benefits of CNT reinforcement can be accessed only if physical fundamentals are understood. Regarding CNT-metal composites little has been done even in the area of experimental synthesis, processing, and characterization. The proposed research will for the first time investigate systematically on CNT reinforced magnesium composite. Experimentally, a novel process to fabricate CNT magnesium composites by using dispersion of CNTs in the melt will be developed. Of particular interest are the dispersion and wettability of different types of CNTs in magnesium melts. Combining with the experiments, the CNT reinforcing mechanisms will be thoroughly investigated. We will assess their validity, determine their efficiency, and understand their interactions with other strengthening mechanisms in complex alloy systems. The basic mechanisms will be evaluated to assess the theoretical potential of CNT reinforcement and to guide the experimental research. Comprehensive characterizations will be carried out to be benchmarked against the theoretical properties.

碳纳米管（CNT）增强材料复合材料因其优异的性能而引起了广泛的关注。然而，仍然缺乏对强化机制以及这些机制如何在给定材料系统中相互作用的理解。只有了解物理基础知识，才能发挥碳纳米管加固的潜在优势。关于碳纳米管-金属复合材料，即使在实验合成、加工和表征领域也鲜有进展。该研究将首次系统地研究碳纳米管增强镁复合材料。通过实验，将开发一种利用 CNT 在熔体中分散来制造 CNT 镁复合材料的新工艺。特别令人感兴趣的是不同类型的碳纳米管在镁熔体中的分散性和润湿性。结合实验，深入研究CNT的增强机制。我们将评估它们的有效性，确定它们的效率，并了解它们与复杂合金系统中其他强化机制的相互作用。将评估基本机制，以评估碳纳米管增强的理论潜力并指导实验研究。将进行综合表征，以理论特性为基准。
