The Anodic Dissolution of a Ni-Base Superalloy
Corrosion, 1983A single phase nickel base superalloy, HASTELLOY(1) Alloy C-276, was anodically polarized in 0.5 N NaCl at 70 C, and the concentrations of metal-ion complexes in solution were determined. Relative dissolution rates of alloying elements were obtained and selectivity coefficients were calculated.

Relation between the microstructure and microchemistry in Ni‐based superalloy
Surface and Interface Analysis, 2012Ni‐based superalloys with biphasic structure (γ + γ′) are widely used for high‐temperature applications, such as disks and blades of gas turbines and aeronautical engines. For these applications, the stability at high temperature is of utmost importance, in particular the coarsening and the morphological changes of γ′ may be seriously detrimental for ...

Phase Transformation and Segregation to Lattice Defects in Ni-Base Superalloys
Microscopy and Microanalysis, 2007Nanostructural features of nickel-base superalloys as revealed by atom probe field ion microscopy (APFIM) and atom probe tomography (APT) are reviewed. The more salient information provided by these techniques is discussed through an almost exhaustive analysis of literature over the last 30 years.

Temperature dependence of ordering in the ? -phase of Ni-based superalloys
Applied Physics A: Materials Science & Processing, 2002Short-range order (SRO) in model ?-phases of several Ni-based superalloys is investigated by elastic diffuse neutron scattering as a function of temperature. The composition of the single-crystalline samples has been modified by small amounts of additional elements like Mo, Re, Ru and W in order to study their influence on SRO, which is clearly ...

Thermal cycle simulation of a Ni-base superalloy
Scripta Materialia, 1996Abstract Thermal cycle simulation techniques have been investigated as a method of studying the effect of cooling rate, from sub-solvus solution heat treatment temperatures, on the microstructure and fatigue properties of Ni-based superalloy specimens. A Smitweld thermal cycle simulator (TCS) and a Gleeble 1500 TCS were used during the investigation.

Combined Cycle Fatigue of Ni-Base Superalloy
Key Engineering Materials, 2011Fatigue life of a cast Ni-base superalloy IN 713LC under combined cycle loading consisting of a superposition of low- and high-cycle fatigue at 800 °C was experimentally determined. No measurable effect of combined cycle was found for studied loading conditions.
