Thesis Abstract

Abstract
The use of additive manufacturing (AM) techniques in the production of metal components has gained significant attention in recent years due to their potential to achieve complex geometries and functional designs. This research project focuses on the analysis of microstructure and mechanical properties of additively manufactured metal alloys, aiming to provide insights into the influence of AM processes on the final properties of metal components. The study encompasses a comprehensive literature review on AM technologies, microstructure characterization techniques, and mechanical testing methods to establish a solid foundation for the research. In the literature review, various aspects related to the AM of metal alloys, such as powder bed fusion, directed energy deposition, and binder jetting processes, are discussed in detail. Additionally, the influence of processing parameters, post-processing treatments, and alloy compositions on the microstructure and mechanical properties of additively manufactured metal alloys is explored. The research methodology section outlines the experimental approach, including sample preparation, microstructure analysis using scanning electron microscopy and X-ray diffraction, and mechanical testing techniques like tensile, hardness, and impact testing. The experimental findings reveal the intricate relationship between processing parameters and the resulting microstructure and mechanical properties of additively manufactured metal alloys. The microstructural analysis provides insights into the grain structure, phase composition, and defects present in the samples, while the mechanical testing results elucidate the tensile strength, hardness, ductility, and fracture toughness of the components. The discussion of findings highlights the key factors influencing the properties of additively manufactured metal alloys, emphasizing the importance of optimizing process parameters to achieve desired performance characteristics. In conclusion, this research project contributes to the growing body of knowledge on the analysis of microstructure and mechanical properties of additively manufactured metal alloys. The findings provide valuable insights for engineers and researchers involved in the development and optimization of AM processes for metal component fabrication. By enhancing our understanding of the relationships between processing conditions, microstructure evolution, and mechanical performance, this study aims to facilitate the advancement of AM technologies in the manufacturing industry, paving the way for the production of high-performance metal components with tailored properties.
