    摘要:

    与外加颗粒法相比,原位自生法制备的颗粒尺寸小、表面干净且与基体界面结合强度高,使得铝基复合材料具有高比强度、高比模量以及良好的强塑性匹配等优势。因此,原位自生铝基复合材料是航空航天结构件轻量化设计的理想材料之一。从原位自生TiB2颗粒增强铝基复合材料制备、组元配比优化设计、性能与强韧化机制等三个方面总结其研究现状,同时梳理了原位自生TiB2颗粒增强铝基复合材料存在问题与未来发展方向,以期望促进原位自生铝基复合材料在民航客机等航空高端领域快速发展。

    Abstract:

    Compared with the ex-situ method, the particles prepared by in-situ method exhibited the characters of small size, clean particle-matrix surface and high strength of the particle-matrix interface, which makes aluminum(Al) matrix composites have the advantages of high specific strength and high specific modulus as well as good strength and plasticity matching. Therefore, in situ Al matrix composites are one of the ideal materials for lightweight design of aerospace structural parts. In this paper, the research status of in-situ TiB2 particle reinforced Al matrix composites was summarized from three aspects: preparation, optimization design of component ratio, mechanical properties and strong mechanism. Meanwhile, the existing problems and future development direction of the present composites were analysed, in order to promote the rapid development of in-situ TiB2 particle reinforced Al matrix composites in the civil aviation passenger aircraft and other aviation high-end fields.
