    “Microstructure of metallic materials produced by additive manufacturing”
4. 概要（Abstract）:
   Additive manufacturing – or 3D printing – has been gaining an important role in production of various materials with complicated shapes and new microstructures. In the field of metallic materials, it has been already used to produce functional parts such as propellers and implants. Therefore, the study of the process of additive manufacturing as well as of the structure and properties of the materials produced in this way together with searching for their mutual relationships, has been very intensive in the last decades and results in improved processing of many products.
   In the present talk, the basic processes of the additive manufacturing will be introduced and documented by videos. The research topic of this talk is focused on the development of the microstructure of additively manufactured metallic materials. It will be shown that the microstructure of Al-based alloys differs substantially from that of pure iron, and the reasons for this difference will be explained using our own experimental results. For example of a maraging steel, it will be shown how the presence of trace elements affects the microstructure of the material and its mechanical properties. From the viewpoint of the macrostructure, metamaterials produced by additive manufacturing will be introduced which represent an important group of metallic products.
