Sumario: | Micro-addition of alloying elements is not only an effective method to improve the overall performance of aluminum matrix composites but also a proven workable low-cost technology in improving the reinforced phase/matrix interface structure and regulating the mechanical property of strength-toughness other than the physical processes such as electromagnetic stirring and ultrasonic vibration, as well as preparation technologies like bimodal structure and biomimetic layered materials, <i>etc</i>. In recent years, the research of alloying elements in TiB<sub>2</sub> particles reinforced aluminum matrix composites has attracted much attention and achieved remarkable results which lay a good foundation for better understanding of its mechanism on the nano-level or even the atomic level. A series of latest developments on the properties of TiB<sub>2</sub>/Al composites by adding alloying elements at home and abroad were summarized, <i>i.e</i>. TiB<sub>2</sub> particle morphology, microstructure and mechanical properties.The mechanism of micro-alloying and its prospect on regulating crack initiation and propagation, exerting intrinsic mechanical properties of micro and nano scale, along with coordinating the dilemma of strength-ductility trade-off were also forecasted, aimed at providing reference for the preparation of high-performance aluminum matrix composites. |
