摘　　要：增材制造技术作为传统材料制备与加工方式的有效补充,有望满足先进制造领域对大尺寸、高性能构件短周期制备的新需求。基于能量束的熔化增材制造在使用商业高强铝合金制备大构件时难以避免凝固缺陷,导致所制备构件的材料力学性能下降。搅拌摩擦类增材制造技术避免了凝固缺陷,增材构件致密、组织均匀、晶粒细小、织构较弱,提升了增材构件材料的综合力学性能。本文对搅拌摩擦类增材制造技术在制备高强铝合金方面的研究与应用进展展开综述,分析了搅拌摩擦类增材制造技术面临的挑战及发展趋势,为相关领域的研究提供有益参考。As an effective supplement to the traditional material preparation and processing methods,additive manufacturing technology is expected to meet the new demand for the short-cycle preparation of large-size and high-performance components in the field of advanced manufacturing.Large components made of commercial high-strength aluminum alloy are difficult to prepare using fusion-based additive manufacturing technologies without solidification defects,which reduce the mechanical properties of the components.The friction stir based solid-state additive manufacturing technologies were able to was avoid solidification defects,and fabricate dense,and fine grained component with weak texture,leading to improvement in the mechanical properties of the fabricate components.This paper reviewed the research progress and the application of friction stir based additive manufacturing technologies,and analyzed the challenges and trends in developing friction stir based additive manufacturing.The objective is to provide useful references for advancing the research in related fields.
