摘要
航空航天、兵器等重大装备大型关键结构整体化设计和一体化制造已成为轻量化和服役性能的重要保障。增材制造作为实现创新结构的变革技术被广泛关注和应用,但高强铝合金、镁合金等轻质高强金属增材制造仍面临诸多挑战。搅拌摩擦以强塑性非熔化方式为此类合金高质量增材制造提供了新的思路和方法,并基于此形成了固相增材制造技术与装备。搅拌摩擦增材制造技术的突出优势迅速引发了全球范围的广泛关注和研究,但当前该技术的基础理论和沉积材料组织性能等尚待进一步厘清。系统梳理了搅拌摩擦增材制造领域的最新研究进展,全面评述了国内外在搅拌摩擦增材制造产热机制、材料流动行为、打印工具设计、工艺参数和组织性能等方面的研究成果及装备开发和工程应用现状。最后,展望了搅拌摩擦增材制造技术的未来机遇和发展趋势。
Integrative design and integrated manufacturing of major equipment’s’large critical structure such as aeronautics,astronautics and weapons provide guarantees of lightweight manufacturing and service performance.As a transformative technology can achieve innovative structure,additive manufacturing has received extensive attention and being applied,nevertheless,additive manufacturing of lightweight and high-strength metals such as high strength aluminium alloy and magnesium alloy faces many challenges.Additive friction stir deposition provides a new thought and method for such kind metals,since its process involves strong plasticity and non-melting,which further facilitates the progress of solid-state additive manufacturing and equipment.Dominant advantages of additive friction stir deposition have aroused worldwide attention and investigation;However,this technology’s basic theory and deposited materials’microstructure evolution and performance need to be clarified.Research progress in additive friction stir deposition was systematically summarized,domestic and foreign research achievements such as heat production mechanism,material flow behavior,design of printing tool,processing parameters,microstructure evolution and performance of additive friction stir deposition were comprehensively reviewed.Finally,future opportunities and development trends of additive friction stir deposition were pointed out.
