The effect of gadolinium and boron on the texture development and magnetic properties of the texture controlled 23Cr–10NiCu duplex stainless steels were studied to develop a high performance neutron and electromagnetic shielding material. The 23Cr–10NiCu base alloy is composed of 60% of austenite and 40% of ferrite, whereas, the 23Cr–10NiCu-0.5Gd-0.8B modified alloy is composed of 66% of austenite, 27% of ferrite and 7% of CrFeB intermetallic compounds. The gadolinium and boron addition to the 23Cr–10NiCu base alloy increased mechanical properties. Microstructure observation showed that the small addition of 0.5 wt% gadolinium and 0.8 wt% boron to the alloy retarded to form texture at the same hot rolling conditions, and improved the maximum magnetism, residual magnetism and coercive force about 3%, 122% and 120%, respectively.
