Thermophysical Properties of Ni-Based Superalloys
2022Simulation of casting and joining processes and experimental planning are closely related to liquid metallic materials' thermophysical properties. Thermophysical properties datasets of Ni-based industrial alloys were analyzed through the application of experimental methods and theoretical models.

Melt spinning Ni-based superalloys
Metals Technology, 1983AbstractThe data relating to the production of tapes by chill-block melt spinning of a Ni-based crystalline superalloy (API) are compared with those presented by previous workers for amorphous and low-melting-point crystalline alloys. Comparisons based on fitting the data to established equations shed light upon the physical significance of the ...

Ni-based superalloys for turbine discs
JOM, 1999Superalloys have been developed for specific, specialized properties and applications. One of the main applications for nickel-based superalloys is gas-turbine-engine disc components for land-based power generation and aircraft propulsion. Turbine engines create harsh environments for materials due to the high operating temperatures and stress levels ...

Atomistic simulation studies of Ni-based superalloys
Journal of Alloys and Compounds, 2021Abstract Ni-based superalloys are key materials for hot-end components of aeroengines. Considering the importance and complex of aeroengine components, the understanding on fundamental mechanisms in Ni-based superalloys has been a long-standing demand and challenge.

Ageing kinetics of Ni-base superalloys
Materials at High Temperatures, 2016In the present work, the degradation of the γ/γ′ microstructure of single crystal Ni-base superalloy, CMSX-8, has been studied experimentally and computationally. Two microstructure evolution processes, referred to as rafting and coarsening, have been decoupled and investigated independently.

Nanoporous Membranes Produced from Polycrystalline Ni-Based Superalloys
Journal of Nanoscience and Nanotechnology, 2010Porous metal membranes are produced from a two phase system in which the discrete cubic gamma'-precipitates connect during self assembly. In the so called rafting process the cubic particles start to coarsen and finally create a network within the gamma-matrix. In a following electrochemical leaching process one of the phases can be removed leaving the

1999
Computer models for designing Ni-base superalloys have been developed. A mathematical model using regression equations based on microstructure and property databases has been established and successfully applied to alloy developments. Several types of Ni-base superalloys including new generation single crystal (SC) superalloys have been designed using ...

Hydrogen Embrittlement of Ni-Based Superalloys
CORROSION 1995, 1995Abstract The hydrogen embrittlement properties of some nickel based superalloys such as C-22, C-276, G-30 and Alloy 625 were studied. The alloys were studied for their susceptibility in annealed, cold worked and aged conditions. The degradation in mechanical properties were evaluated by slow strain rate testing.
