L-PBF And DED Processing Of A Ni-based Superalloy

World PM2022 Proceedings, 2022
Different AM technologies such as PBF-LB and DED do become really attractive for both repair and 3D part manufacturing. In particular, extensive work is in progress for the non weldable nickel-based superalloys which tend to exhibit cracks due to residual stresses build-up during AM thermal cycles.

Kinetics and Mechanisms of γ' Reprecipitation in a Ni-based Superalloy. [PDF]

Sci Rep, 2016
AbstractThe reprecipitation mechanisms and kinetics of γ′ particles during cooling from supersolvus and subsolvus temperatures were studied in AD730TM Ni-based superalloy using Differential Thermal Analysis (DTA). The evolution in the morphology and distribution of reprecipitated γ′ particles was investigated using Field Emission Gun Scanning Electron ...

Clean recycling of spent nickel-based single-crystal superalloy by molten magnesium

Journal of Materials Research and Technology
Nickel-based single-crystal superalloys are designed for extreme conditions due to their superior corrosion and creep resistance properties. However, these pose challenges in the subsequent recycling after reaching their end-of-life. Molten magnesium (Mg)

Substrate Effect on the High Temperature Oxidation Behavior of a Pt-modified Aluminide Coating. Part II: Long-term Cyclic-oxidation Tests at 1,050 C [PDF]

, 2007
This second part of a two-part study is devoted to the effect of the substrate on the long-term, cyclic-oxidation behavior at 1,050 C of RT22 industrial coating deposited on three Ni-base superalloys (CMSX-4, SCB, and IN792).

Mapping the evolution of hierarchical microstructures in a Ni-based superalloy [PDF]

Nature Communications, 2013
Phase separation of γ' precipitates determines the microstructure and mechanical properties of nickel-based superalloys. In the course of ageing, disordered γ spheres form inside ordered (L12) γ' precipitates, undergo a morphological change to plates and finally split the γ' precipitates.
