Thesis Abstract

Abstract
Additive manufacturing (AM) has revolutionized the production of complex components across various industries. Titanium alloys are highly sought after in aerospace, medical, and automotive applications due to their exceptional strength-to-weight ratio and corrosion resistance. However, optimizing the AM parameters for titanium alloy components remains a challenge, as it requires a deep understanding of the material behavior during the additive manufacturing process. This thesis aims to address this challenge by characterizing and optimizing the AM parameters for titanium alloy components. The study begins with a comprehensive review of the current literature on additive manufacturing techniques, titanium alloys, and the factors influencing the mechanical properties of AM-produced components. The literature review highlights the gaps in existing knowledge and sets the foundation for the experimental work to follow. The research methodology section outlines the experimental setup, including the selection of titanium alloy materials, AM machines, and process parameters. Mechanical testing, microstructural analysis, and non-destructive testing techniques are employed to evaluate the properties of the AM-produced titanium alloy components. The findings from the experimental work reveal the influence of various AM parameters, such as layer thickness, laser power, and scanning speed, on the mechanical properties and microstructure of the titanium alloy components. The results demonstrate the importance of optimizing these parameters to achieve components with the desired mechanical properties and structural integrity. The discussion section delves into the implications of the experimental results, highlighting the trade-offs between different AM parameters and their impact on the final quality of the components. The challenges and limitations encountered during the study are also addressed, providing insights for future research in this field. In conclusion, this thesis sheds light on the characterization and optimization of additive manufacturing parameters for titanium alloy components. By understanding the complex interplay between AM parameters and material properties, manufacturers can enhance the performance and reliability of titanium alloy components produced through additive manufacturing processes. The findings of this study contribute to the advancement of AM technology and pave the way for the widespread adoption of titanium alloys in various industrial applications.
