註釋Increased activity in fundamental material development using laser-based metal additive manufacturing (AM) has elicited new demand for higher capability materials, particularly in the area of titanium and its composites owing to titanium's relatively low operating temperature and limited wear resistance. To this end, the current work seeks to understand the composition-processing-structure-properties for titanium matrix composites processed using laser based additive manufacturing. The first chapter is dedicated towards recent developments and strategies in material design using laser-based metal additive manufacturing methods. The subsequent chapters explore the development of a titanium matrix composite composition as well as the processing-microstructure-performance properties of a material that exhibits a unique combination of microstructure and properties when produced with two laser-based AM methods. A subsequent thermal model is utilized to understand the thermal profiles and resulting heat affected zone that forms within components produced using laser-based AM. A subsequent chapter outlines the ability for these processing strategies to additionally influence the cutting tool industry by producing WC-Co based materials with designed reinforcement. Overall, the results of this work are intended to help drive material designers and engineers in the area of laser-based AM by leveraging multiple AM methods and processing strategies. The work presented indicates that titanium-matrix-composites produced using laser-based AM can be designed and processed in variable conditions that can influence performance in many different applications in the biomedical, aerospace, nuclear, and marine environments, among many others.
