摘要

激光粉末床融合（L-PBF）是一种流行的金属增材制造（AM）工艺，用于制造复杂的金属3D部件。马氏体时效钢是AM中使用的金属之一，属于航空航天和工具工业中使用的超高强度钢。在L-PBF工艺中，激光束用于熔化和熔化金属粉末颗粒。这产生了高的热梯度，并且熔池的快速冷却导致柱状晶粒。AM零件的微观结构与传统制造的情况完全不同，这需要AM后热处理。综述了印刷工艺参数和热处理对L-PBF马氏体时效钢300合金组织和力学性能的影响。详细讨论了L-PBF零件的拉伸、冲击、断裂和疲劳性能。

Laser powder bed fusion additive manufacturing of maraging steel: A review

Laser powder bed fusion (L-PBF) is a popular metal additive manufacturing (AM) process used to manufacture complex metallic 3D components. Maraging steel is one of the metals used in AM and it belongs to the class of ultra-high-strength steels used in aerospace and tooling industries. In the L-PBF process, a laser beam is used to melt and fuse the metal powder particles. This creates a high thermal gradient and rapid cooling of the melt pool results in columnar grains. The microstructure of AM part is entirely different from the conventionally manufactured case and this necessitates post-AM heat treatments. The current paper reviews the effects of printing parameters and heat treatment on microstructure and mechanical properties of L-PBF produced maraging steel 300 alloy. Tensile, impact, fracture, and fatigue properties of as-built and heat-treated L-PBF parts are discussed in detail.
