“…Simulations can provide a theoretical foundation for predicting and maybe tailoring the mechanical properties of SMCs fabricated via LBAM. (7) In order for customized SMCs to find their way into commercial use, not only their mechanical performance and underlying deformation mechanisms, but further properties such as e.g. the corrosion resistance also at elevated temperatures are required to be investigated in-depth.…”

“…As a response to the industrial demand for even stronger and, particularly, more wear-resistant Fe-based materials, steel matrix composites (SMCs) have been developed [3]. Owing to the introduction of reinforcements, such as intermetallic compounds, carbides, nitrides, oxides, and borides into the steel matrix, SMCs demonstrate the required mechanical properties needed in service as structural materials for example, in aeronautics, defense and automobile industries [4][5][6][7][8][9]. SMCs profit from the advantageous properties of the hard reinforcing phase and the ductile steel matrix [10].…”

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.
