Microstructures and mechanical behavior of Inconel 718 fabricated by selective laser melting
Krista Amato,Sara M. Gaytan,Lawrence E Murr,E. Martinez,P. W. Shindo,Jennifer Hernandez,S. Collins,Francisco Medina +7 more
TL;DR: In this paper, the Inconel 718 cylinders were fabricated by selective laser melting in either argon or nitrogen gas from a pre-alloyed powder, and they exhibited columnar grains and arrays of oblate ellipsoidal precipitates oriented in a strong [2.0.0] texture determined by combined optical metallography, transmission electron microscopy, and X-ray diffraction analysis.

Precipitation of the δ-Ni 3 Nb phase in two nickel base superalloys
TL;DR: In this article, the precipitation of the metastable δ-Ni3Nb phase has been studied in two niobium bearing nickel base superalloys and the morphology and distribution of precipitates have been examined and the crystallographic orientation relationship between the austenite and the δ phases has been determined.

Low Cycle Fatigue Behavior of Inconel 718 at 298 K and 823 K
D. Fournier,André Pineau +1 more
TL;DR: In this article, the cyclic stress-strain response and the low cycle fatigue life of conventionally heat treated Inconel 718 were studied using optical and electron microscopy.
Journal ArticleDOI
Strengthening of an Al–Cu–Sn alloy by deformation-resistant precipitate plates
TL;DR: In this paper, a variation of the Orowan equation is developed for aluminium alloys strengthened by dispersed, deformation-resistant α precipitate plates, and the quantitative effects of precipitate volume fraction, number density and aspect ratio on increments in orowan strengthening are examined.
Journal ArticleDOI
Influence of uniaxial stress on the morphology of coherent precipitates during coarsening—elastic energy considerations
TL;DR: In this article, the influence of uniaxial applied stress on the morphology of coherent precipitates during coarsening is investigated, using the theory of inclusions and inhomogeneities by Eshelby.

On diffraction contrast from inclusions
Michael F. Ashby,L. M. Brown +1 more
TL;DR: In this paper, the dynamical theory of diffraction contrast is applied to elastic inclusions and the visibility of such inclusions is discussed, and the best conditions for obtaining information about the state of strain around them derived.
