Fabricating Superior NiAl Bronze Components through Wire Arc Additive Manufacturing
Cast nickel aluminum bronze (NAB) alloy is widely used for large engineering components in marine applications due to its excellent mechanical properties and corrosion resistance. Casting porosity, as well as coarse microstructure, however, are accompanied by a decrease in mechanical properties of cast NAB components. Although heat treatment, friction stir processing, and fusion welding were im...
متن کاملWire Arc Additive Manufacturing of AZ31 Magnesium Alloy: Grain Refinement by Adjusting Pulse Frequency
Wire arc additive manufacturing (WAAM) offers a potential approach to fabricate large-scale magnesium alloy components with low cost and high efficiency, although this topic is yet to be reported in literature. In this study, WAAM is preliminarily applied to fabricate AZ31 magnesium. Fully dense AZ31 magnesium alloy components are successfully obtained. Meanwhile, to refine grains and obtain go...
متن کاملMechanical Properties of Austenitic Stainless Steel Made by Additive Manufacturing
Using uniaxial tensile and hardness testing, we evaluated the variability and anisotropy of the mechanical properties of an austenitic stainless steel, UNS S17400, manufactured by an additive process, selective laser melting. Like wrought materials, the mechanical properties depend on the orientation introduced by the processing. The recommended stress-relief heat treatment increases the tensil...
متن کاملEffect of Molten Pool Size on Microstructure and Tensile Properties of Wire Arc Additive Manufacturing of Ti-6Al-4V Alloy
Wire arc additive manufacturing (WAAM) technique is a cost-competitive and efficient technology to produce large structure components in industry domains. Mechanical properties are mainly dominated by the microstructure of the components, which is deeply affected by the molten pool size. In this work, to investigate the effect of the molten pool size on microstructure and mechanical properties ...
متن کاملVibration Assisted Robotic Hot-wire Gas Tungsten Arc Welding (gtaw) for Additive Manufacturing of Large Metallic Parts
Most of the metal additive manufacturing technologies are focused on high cost and high end applications. There is in need, a low cost additive manufacturing technology suitable for low and high end metallic applications. Robotic automated welding can be considered as an alternative to manufactured large scale metal parts with layer by layer approach. However, many obstacles have to be overcome...
