| Abstract Scope |
Metal additive manufacturing (AM), specifically wire arc additive manufacturing (WAAM) has become increasingly popular for applications of large metal components due to the high deposition rate and low equipment costs compared to other metal AM techniques. Nickel aluminum bronze (NAB) has been one alloy that has been valued for its high strength, corrosion resistance, and cavitation resistance. Although WAAM techniques have shown advantages over traditionally cast components, there is a large amount of uncertainty surrounding the processing-structure-property relationships in WAAM metals. Specifically, when rapidly cooled, NAB has fine, face centered cubic (fcc) α phase that is formed from a coarse high-temperature body centered cubic (bcc) β phase, along with various κ precipitates. This work focuses on investigating the effect of cooling rates on the α-lathe size, the κ precipitates, and the reconstructed prior-β grains and the respective impact on mechanical properties in NAB.
