||Over the past decade, additive manufacturing (AM) has been developed from research labs and is being employed in a variety of applications such as aerospace, naval/maritime, nuclear, medicine, and automotive. The unique microstructures and macroscopic defect structures (i.e, porosity, microcracks, grain morphology variability, cellular substructures, and elemental segregation, surface roughness, etc.) produced in AM processes can have strong impacts on the degradation behavior of parts in service. Since the microstructure of AM parts is different from those produced by casting or metal forming, materials response to the corrosive environment is different.
This symposium considers the aqueous corrosion and high-temperature oxidation behavior of structural materials mainly steels, aluminum, titanium, nickel, cobalt, and copper, high entropy alloys, bulk metallic glasses and functional materials used in AM. The topics of presentations are sought to include but not limited to:
• In-process powder contamination and oxidation during AM processes;
• Developing new materials for harsh environments;
• Effects of defect structures and anisotropic microstructure on electrochemical response and high-temperature oxidation behavior of AM parts;
• Corrosion fatigue and stress corrosion cracking in structural materials;
• Influence of post-processing such as heat treatment and surface treatment on corrosion response of the AM parts.
