Abstract

Magnesium and its alloys, as a promising class of materials, is popular in lightweight application and biomedical implants due to their low density and good biocompatibility. Additive manufacturing (AM) of Mg and its alloys is of growing interest in academia and industry. The domain-by-domain localized forming characteristics of AM leads to unique microstructures and performances of AM-process Mg and its alloys, which are different from those of traditionally manufactured counterparts. However, the intrinsic mechanisms still remain unclear and need to be in-depth explored. Therefore, this work aims to discuss and analyze the possible underlying mechanisms regarding defect appearance and elimination, microstructure formation and evolution, and performance improvement, based on presenting a comprehensive and systematic review on the relationship between process parameters, forming quality, microstructure characteristics and resultant performances. Lastly, some key perspectives requiring focus for further progression are highlighted to promote development of AM-processed Mg and its alloys and accelerate their industrialization.

镁及其合金增材制造:工艺-成形-组织-性能关系及机理

镁及其合金因其低密度和良好的生物相容性，在轻量化应用和生物医学植入物中得到广泛应用。镁及其合金的增材制造(AM)越来越受到学术界和工业界的关注。增材制造的逐域局部成形特性使得增材制造的镁合金及其合金具有不同于传统制造镁合金的独特组织和性能。然而，其内在机制尚不清楚，需要深入探讨。因此，本工作旨在通过对工艺参数、成形质量、微观组织特征与最终性能之间关系的全面系统综述，探讨和分析缺陷产生与消除、微观组织形成与演变以及性能改进的可能机制。最后，提出了今后需要重点关注的几个问题，以促进am加工镁合金的发展，加快其产业化进程。

期刊介绍： The International Journal of Extreme Manufacturing (IJEM) focuses on publishing original articles and reviews related to the science and technology of manufacturing functional devices and systems with extreme dimensions and/or extreme functionalities. The journal covers a wide range of topics, from fundamental science to cutting-edge technologies that push the boundaries of currently known theories, methods, scales, environments, and performance. Extreme manufacturing encompasses various aspects such as manufacturing with extremely high energy density, ultrahigh precision, extremely small spatial and temporal scales, extremely intensive fields, and giant systems with extreme complexity and several factors. It encompasses multiple disciplines, including machinery, materials, optics, physics, chemistry, mechanics, and mathematics. The journal is interested in theories, processes, metrology, characterization, equipment, conditions, and system integration in extreme manufacturing. Additionally, it covers materials, structures, and devices with extreme functionalities.
