  • Role of Stoichiometry on Ordering in Ni-Cr Alloys

    Creator:
    Teng, Fei
    Abstract:
    Mechanical property degradation due to isothermal ageing is of potential concern for alloys based on the Ni-Cr binary system (e.g., Inconel 690, 625), particularly in nuclear power applications where component lifetimes can exceed 40 years. In the present research, the disorder-order phase transformation, which is the primary mechanism of ageing,...

  • Role of Alloying on the Thermal Stability of Duplex Stainless Steel

    Creator:
    Garfinkel, David
    Abstract:
    Duplex stainless steels (DSS) are an attractive potential material in nuclear power generation systems due to an excellent combination of corrosion resistance, strength, toughness, and affordability. Thermal embrittlement caused by phase instability in the temperature range of ~300-550°C severely limits the service temperature of DSS. The rate of embrittlement varies...
