梁式工艺广泛用于金属添加剂的制造，但其能力与工业和社会的需求之间存在着很大的差距。例如，凝固问题、各向异性的机械性能以及对粉末属性的限制。非基于光束的添加工艺有望弥合这些差距。在这篇观点文章中，我们介绍和讨论了添加摩擦搅拌沉积，这是一种快速、可扩展的固态工艺，可产生精细的微结构，并具有灵活的进料选择。通过与其他添加剂工艺的比较，我们讨论了它的优点和局限性，以及广泛实施金属添加剂制造的途径。(C)2018 Acta Materialia Inc.由Elsevier Ltd.出版。保留所有权利。
Beam-based processes are popularly used for metal additive manufacturing, but there are significant gaps between their capabilities and the demand from industry and society. Examples include solidification issues, anisotropic mechanical properties, and restrictions on powder attributes. Non-beam-based additive processes are promising to bridge these gaps. In this viewpoint article, we introduce and discuss additive friction stir deposition, which is a fast, scalable, solid-state process that results in refined microstructures and has flexible options for feed materials. With comparisons to other additive processes, we discuss its benefits and limitations along with the pathways to widespread implementation of metal additive manufacturing.
