Effect of Heat Treatment on the Mechanical Properties of Additively Manufactured Metal Alloys

Project Abstract

The additive manufacturing process has revolutionized the field of materials and metallurgical engineering by enabling the production of complex metal components with enhanced design flexibility and reduced lead times. One critical aspect of additive manufacturing is the post-processing heat treatment, which can significantly influence the mechanical properties of the manufactured metal alloys. This research project aims to investigate the effect of heat treatment on the mechanical properties of additively manufactured metal alloys, with a focus on understanding how different heat treatment parameters impact the material characteristics. The study begins with a comprehensive review of the existing literature on additive manufacturing, heat treatment techniques, and the mechanical properties of metal alloys. The literature review highlights the gaps in current knowledge and provides a theoretical framework for the research. The research methodology involves the additive manufacturing of metal alloy specimens using a selective laser melting (SLM) technique, followed by a series of heat treatment processes at varying temperatures and durations. Mechanical testing, including tensile, hardness, and impact tests, will be conducted on the specimens to evaluate changes in their mechanical properties as a result of different heat treatment conditions. The findings from the experimental investigations will be discussed in detail in Chapter Four, focusing on the relationships between heat treatment parameters and the mechanical properties of the additively manufactured metal alloys. The results will be analyzed to identify the optimal heat treatment conditions that lead to improved mechanical performance, such as increased strength, ductility, and toughness. In conclusion, this research project aims to contribute to the understanding of how heat treatment influences the mechanical properties of additively manufactured metal alloys. The insights gained from this study can have implications for optimizing the post-processing techniques in additive manufacturing to achieve desired material characteristics for various engineering applications. The research findings will provide valuable information for researchers, engineers, and industries involved in additive manufacturing and materials engineering.
