The Impact of Additive Manufacturing Techniques on the Functional Properties of Nickel Aluminum Bronze (NAB) Alloys
摘要
Nickel aluminum bronze (NAB) alloys play a critical role in maritime industries due to their outstanding combined properties such as high strength and corrosion resistance in seawater. In previous studies, researchers discovered that the functional properties of NAB samples produced via wire arc additive manufacturing are improved compared to the traditional methods. Hence, this research aims to investigate the influence of the selective laser melting (SLM) technique on the mechanical properties and corrosion performance of NAB specimens. NAB alloys typically contain a Cu-rich phase called α phase with a face-centered cubic (FCC) crystal structure and κ particles that are often categorized based on their chemical composition, physical characteristics, and distribution within the microstructure. In NAB alloys, the manufacturing process highly influences the microstructural characteristics. In the SLM process, the microstructure is refined due to the high cooling rate, therefore, an improvement in the functional properties of NAB specimens such as mechanical properties and corrosion resistance will be expected.
