Abstract

ABSTRACT Despite strong interest from many industrial sectors driving demand and advancements in laser additive manufacturing (LAM) of steels, some issues remain as barriers limiting the current industrial applications, such as defects, residual stress, scattered, inadequate or/and anisotropic properties. To overcome these problems, several effective approaches have been developed to control and/or enhance the properties of LAM produced steel components. To help researchers and engineers attain up-to-date information and knowledge in this rapidly growing area, the present work provides an overview of current research in LAM of steels, in particular austenitic steels, ferritic steels, duplex steels and martensitic steels, with a focus on understanding the interrelation between process, microstructure and mechanical properties. This review also includes substantive discussions on the effects of processing parameters, their interactions and post-LAM treatments on the metallurgy, microstructure and properties. In addition, the advances, ongoing challenges and outlooks in LAM of steels are highlighted.

钢的激光增材制造

摘要尽管许多工业部门对钢材激光增材制造（LAM）的需求和进步产生了浓厚的兴趣，但一些问题仍然是限制当前工业应用的障碍，如缺陷、残余应力、分散、不充分或/和各向异性。为了克服这些问题，已经开发了几种有效的方法来控制和/或提高LAM生产的钢构件的性能。为了帮助研究人员和工程师获得这一快速增长领域的最新信息和知识，本工作概述了目前对钢，特别是奥氏体钢、铁素体钢、双相钢和马氏体钢的LAM研究，重点是了解工艺、微观结构和机械性能之间的相互关系。这篇综述还包括关于工艺参数、它们的相互作用和LAM后处理对冶金、微观结构和性能的影响的实质性讨论。此外，重点介绍了钢的LAM的进展、持续的挑战和前景。
