Laser additive manufacturing of ceramic reinforced titanium matrix composites: A review of microstructure, properties, auxiliary processes, and simulations

The satisfactory integrated performance of titanium matrix composites (TMCs) has rendered them promising candidates in significant industries including aerospace and biomedicine. Laser additive manufacturing (LAM) technology has facilitated the fabrication of titanium-based materials in a more convenient and efficient manner. Microstructure and properties of LAM-fabricated TMCs are influenced by diverse variables, such as process and powder parameters. To enhance the composites, various reinforcement materials have been employed. However, defects and undesired microstructure frequently cause suboptimal properties. Recent research has explored the possibility of enhancing material properties by combining LAM with auxiliary treatment processes. Furthermore, numerical simulations have been employed to optimize the LAM process of TMCs, elucidate mechanisms, and make predictions. This article provides a comprehensive review of the current research on TMCs produced by LAM techniques, highlighting their potential for future development. The technological development and practical application of LAM-fabricated TMCs can be promoted potentially through suggested research endeavors.
