Abstract

Laser-based additive manufacturing (LBAM) has shown great potential in the development of new metallic materials, especially in the design and fabrication of metal matrix composites (MMCs). Steel matrix composites (SMCs) as one MMC-type, have been successfully additively manufactured with full density and good performance. This article reviews emerging studies of LBAM-fabricated SMCs, starting from the methods of feedstock preparation including respective merits and challenges. The mechanisms of phase transformation, grain growth and texture development of the steel matrix, as well as the precipitation of reinforcements during rapid solidification inherent to LBAM are demonstrated. Microstructural features of SMCs with different matrix (austenitic, martensitic, duplex and ferritic) and reinforcement types are discussed. The interrelationship between the composition and physical properties of the composite powder, microstructures and mechanical properties of SMCs are disclosed and the involved strengthening mechanisms are discussed. Lastly, conclusions and outlook focusing on emerging trends of LBAM-fabricated SMCs are presented.

激光增材制造钢基复合材料的原料制备、显微组织和力学性能

激光增材制造(LBAM)在新型金属材料，特别是金属基复合材料(MMCs)的设计和制造方面显示出巨大的发展潜力。钢基复合材料(SMCs)作为mmc的一种，已成功制备出密度大、性能优良的增材复合材料。本文从原料制备的方法，包括各自的优点和挑战出发，综述了lbamm制备SMCs的最新研究。揭示了LBAM快速凝固过程中钢基体的相变、晶粒生长和织构发育以及增强体析出的机理。讨论了不同基体(奥氏体、马氏体、双相和铁素体)和增强类型的SMCs的显微组织特征。揭示了复合粉末的组成和物理性能与SMCs的显微组织和力学性能之间的相互关系，并讨论了所涉及的强化机制。最后，总结并展望了lbam制造的SMCs的发展趋势。
