A duplex stainless steel sheet with 1 wt.% gadolinium was fabricated for a neutron absorbing material with high strength,excellent corrosion resistance, and low cost as well as high neutron absorption capability. The microstructure of the as-cast specimen has typical duplex phases including 31% ferrite and 69% austenite. Main alloy elements like chromium (Cr), nickel (Ni), and gadolinium (Gd) are relatively uniformly distributed in the matrix. Gadolinium rich precipitates were present in the grains and at the grain boundaries. The solution treatment at 1070 ºC for 50 minutes followed by the hot-rolling above 950 ºC after keeping the sheet at 1200 ºC for 1.5 hours are important points of the optimum condition to produce a 6 mm-thick plate without cracking.
