摘要:

本文從鋁基復合材料納米化、構型化、制造技術三個方面，綜述了先進鋁基復合材料研究的新進展，并對其發(fā)展趨勢進行了展望。新型納米增強體可為鋁基復合材料提供高的增強效率，而增強體和鋁基體的納米化則由于一系列尺寸效應賦予復合材料更優(yōu)異的性能；基體晶粒尺寸的雙峰、多峰分布，層狀、網絡等復合構型的設計為其性能最優(yōu)化提供了新的途徑；新型粉末冶金、大塑性變形、增材制造等新技術為新型鋁基復合材料的制備和加工提供了技術基礎�？梢灶A見，性能更優(yōu)異的納米增強體的應用、不同尺度結構效應的發(fā)揮及新型鋁基復合材料制備加工新技術的開發(fā)，將成為未來鋁基復合材料的研究熱點。

Abstract:

This paper reviewed several recent progresses of advanced aluminum matrix composites in the nano reinforcement, nanocrystallization of matrix, architecture design and advanced manufacturing technologies. High-performance nano reinforcements could provide high enhancement efficiency, while the nanocrystallization of the matrices could introduce a serial of nan size effects; the architecture designs (e.g. bimodal or multimodal distributions, laminated or network architectures) provided new routes for property optimization of the aluminum matrix composites; and the advanced manufacturing technologies (e.g. advanced powder metallurgy, severe plastic deformation and additive manufacturing) provided techniques for the preparation and processing of advanced aluminum matrix composites. It can be expected that, the application of nano reinforcements with better properties, structural effects at different scales and new manufacturing technologies would be the hotspot in the future research.
