Abstract Scope |
Currently, it can take several years to go from part concept to production on mission critical additively manufactured components, making broad adoption of this technology quite challenging. Also, for most conventional structural applications, a single alloy composition is used to fabricate the entire component, often compromising in terms of cost and/or performance. A pathway to make AM a substantial manufacturing strategy is to incorporate its unique attributes to fit site-specific performance needs. This is truly a material agnostic concept and may be employed to fabricate graded structural parts – namely using Ti alloys, Ni-base superalloys and Nb/Mo-based refractory alloys. Based on the above-mentioned alloy systems, the current study is a scientific deep dive on AM-based combinational alloy development strategy, geared towards generating hybrid microstructures for site-specific property response. The progress of this work will enhance capabilities to incorporate design optimization strategies and tailor multimodal AM fabrication into future applications. |
