摘要:

金屬基復合材料相較于傳統金屬材料，具有許多單相材料所不具備的優異性能，目前已經被廣泛應用于航空航天、運輸和制造業等領域，并且已經逐漸成為許多高新科技領域的重要材料。高熵合金因其良好的強韌性、高的抗疲勞性、優異的耐磨性和電磁性能，具有重要的實用研究價值。高熵合金顆粒與復合材料金屬基體之間具有金屬間天然的界面結合特性且熱膨脹系數相差較小，能夠克服傳統復合材料生產中出現的界面結合穩定性差、塑韌性不足等缺點，為制備高性能金屬基復合材料提供了思路。圍繞高熵合金顆粒增強金屬基復合材料的研究進展，總結了典型高熵合金體系的組織性能以及高熵合金顆粒增強金屬基復合材料的制備方法、界面和顆粒特征對其微觀形貌和力學性能的影響。

Abstract:

Compared with traditional metal materials, metal matrix composites have many excellent properties that single-phase materials do not have. They have been widely used in aerospace, transportation and manufacturing fields, and have gradually become a kind of important material in many high-tech fields. High�瞖ntropy alloy has important practical research value due to its good strength and toughness, high fatigue resistance, excellent wear resistance and electromagnetic properties. Due to the natural interfacial bonding between high-entropy alloy particles and metal matrix and the small difference in coefficient of thermal expansion, it can overcome the disadvantages of poor interfacial bonding stability and insufficient plasticity and toughness in the production of traditional composite materials, which provides an idea for the preparation of high-performance metal matrix composites. Focusing on the research progress of high-entropy alloy particle reinforced metal matrix composites, this paper summarizes the microstructure and properties of typical high-entropy alloy systems and the effects of the preparation methods as well as interface and particle characteristics of high-entropy alloy particle reinforced metal matrix composites on their micromorphology and mechanical properties.
