| Abstract Scope |
Wire arc additive manufacturing (WAAM) has been shown to be a cost-effective substitute for traditional manufacturing processes, and it can provide unique processing routes for improving the performance of aluminum naval components while increasing manfacturing flexibility. The mechanical properties of WAAM aluminum have been shown to be comparable to castings. We intend to improve this performance by using hybrid WAAM (HWAAM) processing to introduce precipitation strengthening that can be tailored through the control of alloy composition and printing parameters. The proposed study is motivated by the recent findings of Rakhmonov et al., who showed that a high volume of finely-spaced Al(FeMn)Si precipitates can be produced with laser powder bed fusion processing and used to refine the microstructure and improve mechanical properties, even at elevated temperatures where other common precipitates would coarsen. This presentation will investigate the feasibility of translating these findings to HWAAM, which is better suited for expeditionary environments. |
