  • Hafnium alloys as neutron absorbers
    Patent number: 5330589
    Abstract: A hafnium alloy consisting essentially of hafnium and containing Sn by 0.1-1.5 weight %, O by 0.03-0.2 weight %, Fe by 0.01-0.15 weight %, Zr by 0.02-2.0 weight %, and (1) Cr by 0.01-0.15 weight %, and Ni by less than 0.10 weight %, (2) Cr by 0.01-0.15 weight %, Ni by less than 0.10 weight %, and Mo by 0.01-0.2 weight %, (3) Nb by 0.2-1.0 weight %, or (4) Nb by 0.2-1.0 weight %, and Mo by 0.01-0.2 weight % has high neutron-absorbing capacity, high resistance to uniform and nodular corrosion, high tensile and creep strength, and good wear resistance, and is suited to be used as neutron absorber for nuclear power reactors.
