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 $478.8{ pm}11.6$ to $514.2{ pm}29.9MPa$ , whereas elongation of the cast alloy decreased with the addition of gadolinium, from $26.0{ pm}7.1$ to $7.0{ pm}2.5%$ due to the formation of gadolinium based intermetallic compounds. |
