Low Temperature Hot Corrosion Screening of Single Crystal Superalloys [PDF]

Materials, 2018
Single crystal superalloys were screened in Type II molten (Na,K)-sulfate hot corrosion re-coat tests in air +300 ppm SO2 at 700 °C. They exhibited large 20–40 mg/cm2 weight changes, repeated spallation, and non-protective, 25–50 μm thick corrosion layers after 300 h of testing.

Anisotropic Oxidation Resistance in a Ni-Base Single Crystal Superalloy

International Journal of Electrochemical Science, 2015
A study on the anisotropic oxidation resistance in a Ni-base single crystal superalloy was investigated at 1000 °C. Overall, the specimens with (100) face showed a higher oxidation rate compared with the specimens with (110) face.

Evolution of interfacial dislocation network during anisothermal high-temperature creep of a nickel-based superalloy [PDF]

, 2011
The effect of thermal cycling creep on the dislocation networks at the γ/γ′ interfaces in the MC2 superalloy is investigated. Tensile creep tests were performed under thermal cycling and isothermal conditions at low stress (80 MPa) and high temperature ...

Optimizing Scale Adhesion on Single Crystal Superalloys [PDF]

Materials Science Forum, 2001
To improve scale adhesion, single crystal superalloys have been desulfurized to levels below 1 ppmw by hydrogen annealing. A transition to fully adherent behavior has been shown to occur at a sulfur level of about 0.2 ppmw, as demonstrated for PWA 1480, PWA 1484, and Rene N5 single crystal superalloys in 1100-1150 C cyclic oxidation tests up to 2000 h.
