Analysis of combined static load and low temperature hot corrosion induced cracking in CMSX-4 at 550°C

Brooking, Laurie; Gray, Simon; Dawson, K.; Nicholls, John R.; Simms, Nigel J.; Sumner, Joy; Tatlock, G. J. (Elsevier, 2019-10-18)

A CMSX-4 3-point bend specimen was statically loaded under hot corrosion conditions and SEM, (S)TEM and EDX techniques were used to analyse the cracking generated. Sulphur, chlorine, sodium and oxygen were found at the ...
Corrosion fatigue testing: the combined effect of stress and high temperature corrosion

Chapman, Neil; Brooking, Laurie; Sumner, Joy; Gray, Simon; Nicholls, John R. (Taylor & Francis, 2017-10-20)

A corrosive environment can have a detrimental effect on the fatigue life of a material due to a change in failure mechanism. Attempts have been made to replicate this change on nickel-base superalloy CMSX-4 cast in the ...
Effect of stress state and simultaneous hot corrosion on the crack propagation and fatigue life of single crystal superalloy CMSX-4

Brooking, Laurie; Gray, Simon; Sumner, Joy; Nicholls, John R.; Marchant, G.; Simms, Nigel J. (Elsevier, 2018-05-03)

Operating conditions within industrial gas turbines are changing in response to pressures to reduce environmental impact and enable use of renewable sources. This is driving an increase in the operational temperatures and ...
Interaction of hot corrosion fatigue and load dwell periods on a nickel-base single crystal superalloy

Brooking, Laurie; Gray, Simon; Sumner, Joy; Nicholls, John R.; Simms, Nigel (Elsevier, 2018-07-25)

The effects of type II hot corrosion on the fatigue resistance of turbine blade superalloys is of growing interest as gas turbine (GT) original equipment manufacturers (OEMs) strive to optimise the operational efficiencies ...
Stress corrosion of Ni-based superalloys

Brooking, Laurie; Sumner, Joy; Gray, Simon; Simms, Nigel (Taylor & Francis, 2017-12-03)

The development of gas turbines to increase fuel efficiency is resulting in progressively higher operating temperatures in the under platform regions of the blades. These regions have traditionally been considered low risk ...
