For nickel-based superalloys subjected to high temperatures and oxygen-rich environments,
mechanical loading in combination with oxygen diffusion along grain boundaries leads to an …

Hexagonal boron nitride-reinforced Inconel 718 (h-BN/IN718) composites were fabricated
using a laser powder bed fusion (LPBF) technique to treat a nanosheet-micropowder …

Fatigue-creep tests were carried out on bare and salt-coated of DZ125 superalloys samples
at 850° C. The fatigue lifetime of a corroded alloy was reduced by more than 80% as the …

The fatigue behavior and damage mechanisms of Inconel 718 are investigated and
discussed under thermomechanical fatigue (TMF) and isothermal fatigue (IF) test conditions …
