Abstract Scope |
Laser Directed Energy Deposition presents an exciting new opportunity for alloy development using in-situ powder mixing via multiple powder feed hoppers. This technique alloys for both novel alloy development and the fine-tuning of alloy compositions for additive manufacturing with unprecedented pace and reduced cost by completely circumventing the traditional alloy development cycle. Only a few powder compositions would be needed to create an incredibly wide range of resulting alloy compositions. Further advancement can be realized through the use of thermodynamic modeling to guide the process. As an example, silicon content in an aluminum alloy could be optimized precisely for additive manufacturing by using only two different powders. Alternatively, a stainless steel alloy could be optimized to limit delta ferrite formation upon rapid cooling by varying chromium and nickel content. |
