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 کاملOptimization of Operations in a Steel Wire Manufacturing Company
The project was conducted in a high quality steel wire manufacturing company with the production capacity of over 120,000 tones/annum. The wire drawn from the high speed wire drawing (KOCH) machine is fed as the raw material for BEKEART (zinc coating galvanization) furnace. The problem faced by the company is the variability in the amount of input to the furnace, which results from the breakdow...
متن کاملBlue-light hazard from CO2 arc welding of mild steel.
OBJECTIVES The objective was to quantify the blue-light hazard from CO(2) arc welding of mild steel. METHODS The spectral radiance of arcs in CO(2) arc welding of mild steel was measured for solid and flux-cored wires at welding currents of 120-480 A. Effective blue-light radiance and the maximum acceptable exposure duration were calculated from the spectral radiance using their definitions i...
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 ...
