摘要

随着航空航天等行业对轻量化、高性能材料需求的不断增长,金属基复合材料市场规模持续攀升。其中,SiC颗粒增强铝基复合材料（SiCp/Al复合材料）凭借高比强度、高比刚度等诸多优势,在航空航天等领域得到广泛应用,材料的断裂韧性备受关注。本文深入研究了SiCp/Al-Cu-Mg复合材料断裂韧性的影响因素及解决措施。从铝合金基体、SiC颗粒、铝合金基体与SiC颗粒的界面作用三方面对核心性能及关键工艺进行了简要分析,并介绍了对应的解决措施。最后,以SiCp/Al复合材料锻件为例,总结了完整工艺路线及材料在制备生产中的性能变化。

Abstract

With the growing demand for lightweight and high-performance materials in aerospace and other industries, the market size of metal matrix composites continues to rise. Among them, SiC particle-reinforced aluminum matrix composites (SiCp/Al composites) are widely used in aerospace and other fields due to their advantages such as high specific strength and high specific stiffness, and the fracture toughness of materials has attracted much attention. In this paper, the influencing factors and solutions of fracture toughness of SiCp/Al-Cu-Mg composites are deeply studied. The core properties and key processes are briefly analyzed from three aspects of aluminum alloy matrix, SiC particles, aluminum alloy matrix and SiC particles, and the corresponding solutions are introduced. Finally, taking SiCp/Al composite forgings as an example, the complete process route and the performance changes of the material in preparation and production are summarized.
