Abstract
A new Wire-Arc Additive Manufacturing (WAAM) technique is used to produce Nickel Aluminum Bronze (NAB) components for marine applications in view to mitigate the problems that typically arise in a cast microstructure . In cast condition, the alloy typically exhibits microstructure that consists of an FCC Cu-rich solid solution (or α-phase), some retained β-phase, and several intermetallic phases collectively referred to as κ-phase. This study aims to characterize the crystal structures of the various κ-phases or precipitates, their distribution, morphology, orientation relationships with the α-matrix, and their chemical compositions in WAAM-NAB alloy using electron microscopy . The precipitation of κ-phase differs in morphology and chemical composition to those present in a cast NAB . In addition, some uniaxial tensile coupons were machined out of the WAAM-NAB samples, where tensile mechanical properties are superior to those of cast NAB . The effects of microstructural differences in both alloys on the mechanical properties are correlated.
