Abstract
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.
