Journal ArticleDOI
Additive manufacturing of steels: a review of achievements and challenges
TL;DR: A comprehensive review of the performance of AM steels as a function of these unique micro-structural features is presented in this paper, highlighting that a wide range of steels can be processed by AM.
Journal ArticleDOI
A novel approach for site-specific atom probe specimen preparation by focused ion beam and transmission electron backscatter diffraction
TL;DR: This paper presents the first successful application of a combined focused ion beam (FIB)/t-EBSD preparation of site-specific APT specimens using the example of grain boundary segregation in technically pure molybdenum.
Journal ArticleDOI
Effect of cyclic rapid thermal loadings on the microstructural evolution of a CrMnFeCoNi high-entropy alloy manufactured by selective laser melting

TL;DR: In this paper, an electron microscopy-based investigation of a CrMnFeCoNi high-entropy alloy produced by selective laser melting is presented, which reveals a remarkable hierarchy of microstructures including the formation of nanocrystalline grains, elemental segregation and precipitation, cellular dislocation structures, deformation twinning, and deformation induced phase transformation.
Journal ArticleDOI
On conventional versus direct ageing of Alloy 718
TL;DR: In this article, a correlative microscopy approach was used to identify the detailed microstructural evolution during conventional versus direct aging of Ni-based superalloy, and the results confirmed higher dislocation densities, lower δ-phase volume fractions and the absence of selected γ-matrix grain growth.
Journal ArticleDOI
Origin of high temperature oxidation resistance of Ti–Al–Ta–N coatings
R. Hollerweger,Helmut Riedl,J. Paulitsch,M. Arndt,Richard Rachbauer,Peter Polcik,Sophie Primig,Paul H. Mayrhofer +7 more
TL;DR: In this article, the authors have developed arc-evaporated Ti 1−x−y Al x Ta y N coatings with various Al (x = 0.50−0.65) and Ta (y= 0.00-0.15) contents.
