 Abstract
CD4MCU duplex stainless steel with gadolinium was fabricated as a neutron absorbing material by the air induction melting method. The gadolinium formed intermetallic compounds of Cu-Gd-Fe. There were no significant differences in hardness or ultimate tensile strength between experimental alloys. With the addition of gadolinium the yield strength of the cast alloy significantly increased, from to , whereas elongation of the cast alloy decreased with the addition of gadolinium, from to due to the formation of gadolinium based intermetallic compounds.
