Thesis type APPLIED RESEARCH, EXPERIMENTAL DESIGN, EXPERIMENTAL LABORATORY
Description Additive manufacturing of metallic materials is rapidly emerging in many industries, proving particularly valuable in aerospace, military and racing. The technology is prized for its ability to create components with incredibly complex designs in a surprisingly simple way, paving the way for innovative and hitherto unexplored solutions.
However, additive printing processes take a considerable amount of time to complete. To optimize production time and facilitate technology transfer to companies, an alternative solution has been developed: the use of hot isostatic pressing (HIP). This approach significantly reduces the production time of metal components, opening up new possibilities.
The core of this thesis work lies in the strategic introduction of defects during pressing, which will then be eliminated by subsequent HIP treatment. Through the application of heat and high pressures via an inert gas, internal defects are eliminated and, at the same time, the components are subjected to heat treatment, all in one cycle, saving considerable time and effort.
Optimization of this procedure is crucial and is the candidate's main goal. Through the use of both traditional and advanced laboratory techniques, the candidate will have the opportunity to characterize the various samples made available. The goal is to obtain the best results both microstructurally and mechanically, ensuring a rigorous and meticulous approach.
In conclusion, this project offers an opportunity to take on an exciting challenge in the field of additive printing of metallic materials, paving the way for new perspectives and optimization of a promising process. Leveraging the candidate's skills and state-of-the-art laboratory techniques will yield outstanding results and leave a significant footprint in the field of high-quality component manufacturing.
