  • Effect of NaCl and SO2 on the stress corrosion cracking of CMSX-4 at 550°C 
    Duarte Martinez, Fabian; Syed, Adnan; Dawson, K.; Tatlock, G. J.; Morar, N. I.; Kothari, M.; Tang, C.; Leggett, J.; Mason-Flucke, J. C.; Gibson, G.; Nicholls, Nicholls, John R.; Gray, Simon; Castelluccio, Gustavo M. (Taylor and Francis, 2023-05-01)
    In the pursuit of more efficient gas turbine engines, components are required to operate for longer times at elevated temperatures. This increased time in service, together with a complex loading regime, can expose the ...
  • Environmentally assisted cracking of a single crystal nickel-based superalloy 
    Dawson, Karl; Duarte Martinez, Fabian; Gray, Simon; Nicholls, John; Gibson, G.; Leggett, J.; Tatlock, G. J. (Taylor and Francis, 2023-03-03)
    Single crystal material, of CMSX-4® alloy composition, was cast and secondary orientation was controlled at the machining stage, to produce c-ring cross-section tubes with known crystallographic orientations. The c-ring ...
  • Investigation into the effects of salt chemistry and SO2 on the crack initiation of CMSX-4 in static loading conditions 
    Martinez, Fabian Duarte; Morar, Nicolau I.; Kothari, Maadhav; Gibson, G.; Leggett, J.; Mason-Flucke, J. C.; Nicholls, John R.; Castelluccio, Gustavo M.; Gray, Simon (Springer, 2020-08-29)
    Although evidence exists of the potential impact of stress, co-incident with corrosive environments at high temperature, for single crystal turbine blades, the mechanism responsible is not fully understood. This work ...
  • Measurement and evaluation of co-existing crack propagation in single-crystal superalloys in hot corrosion fatigue environments 
    Brooking, L.; Ferguson, C.; Mason-Flucke, J.; Gibson, G.; Leggett, J.; Palmer, I.; Nicholls, John R.; Gray, Simon (Springer, 2021-08-29)
    Gas turbines blades are required to operate at high temperatures while being subjected to stress and corrosive environments. These demanding conditions have led to the need to better understand the interactions between ...
