加法制造(AM)迅速改变了许多行业的大小规模生产环境。通过从头开始重新设想部件，而不局限于传统制造技术带来的挑战，研究人员和工程师开发了新的设计策略，以解决全球范围内的大规模材料和设计问题。这在合金设计领域尤其如此，在这一领域，新的金属材料历来是通过繁琐的工艺和程序开发出来的，主要基于铸造方法。随着定向能沉积(DED)和基于粉末床熔化(PBF)的AM的出现，可以以比以往更低的成本和更短的交货期快速地创新和评估新合金。本文详细介绍了主要使用基于激光的AM的合金设计的优势、挑战、应用和前景可以预见，工业界和学术界的研究人员可以利用这项工作来设计利用金属AM工艺的新合金，以满足当前和未来的各种应用。
Additive manufacturing (AM) has rapidly changed both large-and small-scale production environments across many industries. By re-envisioning parts from the ground up, not limited to the challenges presented by traditional manufacturing techniques, researchers and engineers have developed new design strategies to solve large-scale materials and design problems worldwide. This is particularly true in the world of alloy design, where new metallic materials have historically been developed through tedious processes and procedures based primarily on casting methodologies. With the onset of directed energy deposition (DED) and powder bed fusion (PBF)-based AM, new alloys can be innovated and evaluated rapidly at a lower cost and considerably shorter lead time than has ever been achieved. This article details the advantages, challenges, applications, and perspectives of alloy design using primarily laser-based AM. It is envisioned that researchers in industry and academia can utilize this work to design new alloys leveraging metallic AM processes for various current and future applications.
