Material science is the key of the society evolutionFor decades, the society has been moving forward with the knowledge of how to utilize materials in a smarter way. Nowadays, sustainability is an important issue that everyone should be aware of in different technology development. Additive manufacturing, also known as 3D printing, shows a great potential of energy efficiency, and the design freedom turns a new page of manufacturing technologies. However, wide variety of knowledge remains unknown from the material science perspectives, hence, my research will try to solve this big puzzle step by step.
Material behavior and design of additively manufactured components (3D printing)Via fundamental study of additive manufacturing (AM), the long-term goal is to bring AM techniques into real application. There are two main topics within my PhD work, one is the anisotropic materials behavior and another one is the thin-walled effect of AM component. I am working with several techniques for materials characterization, including electron microscopes (SEM and TEM), EBSD, hardness measurements, high temperature tensile testing and fatigue study. I am also working on neutron experiment for texture study and in-situ mechanical behavior study. Combined with lab scale experiments, I am aiming for a full-scale study of deformation mechanisms in AM components.
