| Abstract Scope |
Nickel aluminum bronzes (NABs) are microstructurally complex alloys which typically contains α-phase (Copper), some retained β-phase, and four types of κ-intermetallic phases in the as-cast condition. NABs are widely used in marine and aerospace industries, and also find applications in production of pressure vessels, condenser systems, and desalination plants where the high-temperature (423-523 K) properties are important to assess. In the present study, a wire-arc additive manufacturing (WAAM) technique was used to produce NAB square bars to minimize porosity and thereby achieve superior properties. In a view to correlate the local mechanical properties with the microstructure at ambient and elevated temperatures (i.e. 298 K to 523 K), semi-destructive instrumented nano-indentation along with optical and scanning electron microscopies were employed on the wire-arc additive manufactured NAB. The effects of indentation size, indentation strain rate (i.e. strain rate sensitivity), and their dependencies upon indentation depth were then correlated. |
