Microstructural Material Analysis of Superalloy Inconel 792-5A after High Temperature Exposition

Communications, 2009
Aerospace industry often uses nickel superalloys for blades of jet engine turbines. The reason is that this material can satisfy numerous extreme requirements, such e.g. strength even at very high temperatures, resistance to fatigue damage, resistance to

In‐Situ Construction of Multi‐Scale Heterogeneous Structures in L‐DED IN718 Coatings via WMoTaNb Incorporation for Enhanced Strength‐Toughness Synergy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.

Improved high-temperature-strength nickel-base superalloy [PDF]

, 1969
Nickel-base superalloy has a strength of 20,000 psi at 2,200 degrees F, approximately double the strength of the strongest available cast nickel-base alloys. It is not subject to the formation of embrittling phases upon long time exposure at intermediate

Towards low-friction and wear-resistant plasma sintering dies via plasma surface co-alloying CM247 nickel alloy with V/Ag and N

MATEC Web of Conferences, 2015
Nickel based superalloys have good oxidation and creep resistance and hence they can function under high mechanical stress and high temperatures. However, their undesirable tribological behaviour is the major technical barrier to the challenging high ...
