Abstract

Iron-based shape memory alloys (Fe-SMAs), traditionally manufactured, are favored in engineering applications owing to their cost-effectiveness and ease of fabrication. However, the conventional manufacturing process of Fe-SMAs is time-consuming and raw-material-wasting. In contrast, additive manufacturing (AM) technology offers a streamlined approach to the integral molding of materials, significantly reducing raw material usage and fabrication time. Despite its potential, research on AMed Fe-SMAs remains in its early stages. This review provides updated information on current AM technologies utilized for Fe-SMAs and their applications. It provides an in-depth discussion on how printing parameters, defects, and post-printing microstructure control affect the mechanical properties and shape memory effect (SME) of AMed Fe-SMAs. Furthermore, this review identifies existing challenges in the AMed Fe-SMA approach and proposes future research directions, highlighting potential areas for development. The insights presented aim to guide improvements in the material properties of AMed Fe-SMAs by optimizing printing parameters and enhancing the SME through microstructure adjustment.

铁基形状记忆合金快速成型综述

传统制造的铁基形状记忆合金（Fe-SMA）因其成本效益高、易于制造而在工程应用中备受青睐。然而，铁基形状记忆合金的传统制造工艺既耗时又浪费原材料。相比之下，快速成型制造（AM）技术提供了一种简化的材料整体成型方法，可显著减少原材料用量和制造时间。尽管具有潜力，但有关 AMed Fe-SMA 的研究仍处于早期阶段。本综述提供了当前用于铁-SMA 的 AM 技术及其应用的最新信息。它深入探讨了打印参数、缺陷和打印后微结构控制如何影响 AMed Fe-SMA 的机械性能和形状记忆效应 (SME)。此外，本综述还指出了 AMed Fe-SMA 方法中的现有挑战，并提出了未来的研究方向，同时强调了潜在的发展领域。本文提出的见解旨在通过优化印刷参数和调整微观结构来提高 SME，从而改善 AMed Fe-SMA 的材料性能。

期刊介绍： Crystals (ISSN 2073-4352) is an open access journal that covers all aspects of crystalline material research. Crystals can act as a reference, and as a publication resource, to the community. It publishes reviews, regular research articles, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on article length. Full experimental details must be provided to enable the results to be reproduced. Crystals provides a forum for the advancement of our understanding of the nucleation, growth, processing, and characterization of crystalline materials. Their mechanical, chemical, electronic, magnetic, and optical properties, and their diverse applications, are all considered to be of importance.
