PURPOSE:To manufacture an Hf alloy having satisfactory resistance to corrosion by water or steam at high temp. and pressure by adding a specified total amount of Fe and Nb to Hf. CONSTITUTION:An Hf alloy consisting of 0.02-7.0wt% in total of Fe and/or Nb and the balance essentially Hf is manufactured. The Hf alloy has superior resistance to corrosion by water or steam at high temp. and pressure without deteriorating the workability or neutron absorbing power. The alloy is used as a material for controlling a light-water reactor. |
