Abstract Scope |
The growth of additive manufacturing (AM) applications has led to a demand for alloy powders suited for these advanced processing methods. Atomization is the most common process for producing powders for AM. Most often the powders used for AM are pre-existing alloys developed for conventional manufacturing processing methods, e.g. wrought plate. The processing conditions during AM, i.e., rapid solidification and high-temperature gradients, lead to microstructures and mechanical properties different from the wrought material. Therefore, to explore the full potential of AM and to achieve mechanical properties equivalent or superior to those of conventional manufacturing methods, the development of novel AM-suitable alloy powders is critical. In this talk, we will provide a comprehensive look into the recent advances in the field of alloy design of new alloy powders and modification of pre-existing metallic powders produced by gas atomization to advance the mechanical properties of components built up by AM. |
