Typical corrosion resistant nickel based super alloys are a solid solution Nickel whilst few are precipitation hardened materials uch as In 718, 625 and X750. However Ni alloys significantly consist of other alloying elements, still nickel retains its FCC structure from the nickel base element content. Therefore many of these alloys offer outstanding ductility, malleability … Continue reading Stress corrosion cracking behavior of nickel base alloys
Nitric acid is a strong oxidizing agent hence, alloys offering the excellent resistance are those which produce passive oxide layers. The alloys containing crucial magnitude of chromium provide superior resistance as compare to those having lesser Cr content. While nickel based alloys provide high resistance to pure nitric acid,these are specifically effective in the combined … Continue reading Nickel based alloys- Performance in Nitric acid
The study includes evaluation of three major nickel based alloys such as Inconel 617, Incoloy 800 and Hastelloy X to determine their suitability for use in the future nuclear plants that are under design. The various components of nuclear reactors such as control rods, steam generators and heat exchangers are made from the high performance alloys. These … Continue reading Nickel alloys for high temperature heat exchangers in reactors
