Thesis Abstract

Abstract
The rapid advancement in additive manufacturing technology has revolutionized the way metal components are produced, offering new opportunities for enhanced design flexibility and material performance. This thesis investigates the microstructure and mechanical properties of additively manufactured metal alloys to understand the influence of processing parameters on the final product characteristics. The study focuses on analyzing the microstructural features, such as grain size, porosity, and phase distribution, and their correlation with the mechanical properties, including tensile strength, hardness, and ductility. Chapter 1 provides an introduction to the research topic, outlining the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter 2 presents a comprehensive literature review covering ten key aspects related to additive manufacturing, microstructure characterization, mechanical property evaluation, and the relationship between microstructure and properties in metal alloys. Chapter 3 details the research methodology, which includes the selection of materials, additive manufacturing processes, microstructural analysis techniques, mechanical testing methods, data collection procedures, and statistical analysis tools. The chapter also discusses the experimental setup, sample preparation, testing protocols, and data interpretation strategies employed in the study. In Chapter 4, the findings from the experimental investigations are presented and discussed in detail. The microstructural features of the additively manufactured metal alloys are analyzed, and their effects on the mechanical properties are evaluated. The relationships between processing parameters, microstructure, and mechanical properties are elucidated through a systematic analysis of the experimental data. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications, and providing recommendations for future research directions. The study contributes to the understanding of the microstructure-property relationships in additively manufactured metal alloys and offers insights into optimizing processing parameters to achieve desired material characteristics. Overall, this research enhances the knowledge base in the field of materials science and metallurgical engineering, paving the way for the development of advanced metal components with tailored microstructural and mechanical properties through additive manufacturing technologies.
