| Abstract: | In this paper,the recent development of rapidly solidified ultra-nigh strength aluminum alloys is reviewed,based on the reviewing of traditional aluminum, Rapid solidification processing could improve the mechanical propertiesof ultra-high strength aluminum alloy, such improvements are mainly associated with large solid solubility extensions of alloying elements, reduced macro- and micro-segregation, refinement of the alloy grain size. Finally, some new viewpoints on its application and future prospects are discussed. |
