Abstract

Additive manufacturing (AM), as a revolutionary technology, enables the fabrication of complex shape memory alloy (SMA) components with unprecedented degrees of freedom, thus providing tremendous opportunities for developing modern manufacturing and transforming traditional manufacturing. Herein, this review aims to broaden ideas for preparing AM-built SMAs with high performance and multifunctionality through elucidating of the current advancements from the perspectives of the microstructure, properties, and prospects. It is concluded that the columnar grains formed by epitaxial solidification, and the prominent microstructure characteristics during printing, are modulated by different scanning parameters. The combined effects of microstructures, such as precipitates, dislocations, twins and stacking faults, can lead to desirable materials with excellent and stable shape memory effect and superelastic effect. Finally, further breakthroughs in materials, technologies, properties and methods are needed to facilitate applicability in various industries.

增材制造形状记忆合金的最新进展

快速成型制造（AM）作为一项革命性技术，能够以前所未有的自由度制造复杂的形状记忆合金（SMA）部件，从而为发展现代制造业和改造传统制造业提供了巨大机遇。在此，本综述旨在通过从微观结构、性能和前景的角度阐明当前的进展，为制备具有高性能和多功能性的 AM 制造 SMA 拓宽思路。研究认为，外延凝固形成的柱状晶粒以及打印过程中突出的微观结构特征受不同扫描参数的影响。析出物、位错、孪晶和堆叠断层等微观结构的综合效应，可导致理想的材料具有优异、稳定的形状记忆效应和超弹性效应。最后，还需要在材料、技术、性能和方法方面取得进一步突破，以促进其在各行各业的应用。
