Abstract
Official abstract text for this publication.
The disclose relates to ordered Alloy 690 comprising: a matrix that includes a short range order (SRO) in a state in which nickel (Ni) is enriched, and chromium (Cr) and iron (Fe) are depleted, and the ordered Alloy 690 is characterized by having excellent resistance to stress corrosion cracking and improved thermal conductivity due to agglomeration of nickel (Ni) atoms, as compared with the unordered Alloy 690.
First claim
Opening claim text (preview).
1 . Ordered Alloy 690, comprising: a matrix that includes a short range order (SRO) in a state in which nickel (Ni) is enriched, and chromium (Cr) and iron (Fe) are depleted. 2 . The ordered Alloy 690 according to claim 1 , wherein the content of the enriched nickel (Ni) is increased by 2% by atomic weight or higher as compared with the content of nickel (Ni) before enrichment. 3 . The ordered Alloy 690 according to claim 1 , wherein the short range order contains 65% to 85% by atomic weight of nickel (Ni); 8% to 28% by atomic weight of chromium (Cr); and 2% to 8% by atomic weight of iron (Fe). 4 . The ordered Alloy 690 according to claim 3 , wherein the short range order further contains, in an amount of greater than 0% to 3% by atomic weight, one or more atoms selected from the group consisting of manganese (Mn), aluminum (Al), silicon (Si), carbon (C), sulfur (S), and copper (Cu). 5 . The ordered Alloy 690 according to claim 1 , wherein the short range order formed in the matrix has a density of 0.0010/nm 3 to 0.0500/nm 3 . 6 . The ordered Alloy 690 according to claim 1 , wherein the ordered Alloy 690 has a high-temperature thermal conductivity at 300° C. which is improved by 8% or higher as compared with the unordered Alloy 690. 7 . The ordered Alloy 690 according to claim 1 , wherein the ordered Alloy 690 has a measured crack length of about 1,000 μm/mm 2 or shorter when deformed at a slow strain rate of 5×10 −8 /s in simulated water environment (water containing 18 cc/kg H 2 ) of a nuclear power plant at 360° C.
