Microstructure Development in Duplex Stainless Steels from Additive Manufacturing with Coaxial Directed Energy Deposition and Heat Treatment

Duplex stainless steels are widely used in offshore oil and gas, maritime, process, and nuclear industries as they deliver high corrosion resistance, toughness, and ductility, but they are sensitive to formation of brittle microstructures during additive manufacturing. This study has explored the mi...
