摘要
航空铝合金作为航空器机体结构中最重要的结构材料之一,是我国国防科技工业发展、现代化经济体系建设、深入实施制造强国战略的重要物质基础。当前国际上已发展形成高强高韧铝合金、高比强/高比模铝合金、含钪高性能铝合金等三类主要航空铝合金体系,新一代高性能合金研究、高灵活度制备加工以及数据驱动的高效合金设计是主要的发展趋势。当前我国航空铝合金产业与国际发达国家总体“并跑”、部分“跟跑”,特别是在日趋复杂的国际国内宏观形势下,发展机遇与挑战并存,自主创新能力难以支撑航空铝合金材料创新引领、部分品种材料及装备“卡脖子”问题突出、产品国际市场竞争力不足、测试和应用数据积累及过程管控等基础体系能力短板尚存等问题更为突出。需从航空铝合金材料竞争力提升、新材料研发先行、高效上下游合作研发、新材料应用推广、材料指标和应用指标评价体系建立等方面发力,提升我国航空铝合金产业创新发展水平。
Aviation-grade aluminum alloy is one of the most important structural materials for aircraft body structure.It is the material basis for developing national defense industry,constructing a modern economic system,and strengthening the manufacturing sector of China.Aluminum alloys with high strength/toughness,high specific strength/modulus,and Sc addition have been developed in the recent decades.At present,research on next-generation alloy design,processing methods,and new alloy research and development paradigm have been drawing attention.The aviation-grade aluminum alloy industry in China has been developing rapidly.Especially in the increasingly complex international and domestic macro situation,development opportunities and challenges coexist.However,deficiencies are becoming increasingly apparent,such as lacking independent innovation capability to support the leadership of aviation-grade aluminum alloy materials,prominent risks of specific materials and equipment,lacking competitiveness in the international market,and the accumulation of test and application data.It is necessary to improve the competitiveness of aviation-grade aluminum alloy materials,develop new materials,cooperate with upstream and downstream research and development,promote the application of new materials,and establish material and application evaluation systems to improve the innovation and development of the aviation-grade aluminum alloy industry in China.
