Suppression of Grain Boundary Nitrogen Degradation by Boron in Superalloys
C. Crabb, G. Topore, J. O. Douglas +3
Superalloys enable the hottest sections of jet engines to operate at high temperatures, but environmentally assisted degradation limits their lifetime. In polycrystalline alloys, n…
Fracture energy of 6H-SiC at the microscale: effects of testing geometry and notch preparation
Zhuoqi Lucas Li, Siyang Wang, Ao Li +5
Micromechanical testing enables small-scale fracture energy measurements, but values depend strongly on geometry and specimen preparation. Here, the fracture energy of the single-c…
A versatile and reproducible cryo-sample preparation methodology for atom probe studies
Eric V. Woods, Mahander P. Singh, Se-Ho Kim +5
Repeatable and reliable site-specific preparation of specimens for atom probe tomography (APT) at cryogenic temperatures has proven challenging. A generalized workflow is required…
Characterization of local deformation around hydrides in Zircaloy-4 using conventional and high angular resolution electron backscatter diffraction
Ruth M. Birch, James O. Douglas, T. Ben Britton
Zircaloy-4 is used as a fuel cladding material for water reactors, as it has good mechanical properties, corrosion resistance, and a low thermal neutron absorption cross section. H…
In-situ sputtering from the micromanipulator to enable cryogenic preparation of specimens for atom probe tomography by focused-ion beam
James O. Douglas, Michele Conroy, Finn Giuliani +1
Workflows have been developed in the past decade to enable atom probe tomography analysis at cryogenic temperatures. The inability to control the local deposition of the metallic p…
Effect of alloying on the microstructure, phase stability, hardness and partitioning behavior of a new dual-superlattice nickel-based superalloy
C. Rodenkirchen, A. K. Ackerman, P. M. Mignanelli +10
A novel y-y'-y" dual-superlattice superalloy, with promising mechanical properties up to elevated temperatures was recently reported. The present work employs state of the art chem…
Nano-scale imaging of the full strain tensor of specific dislocations extracted from a bulk sample
Felix Hofmann, Nicholas W. Phillips, Suchandrima Das +5
Lattice defects play a key role in determining the properties of crystalline materials. Probing the 3D lattice strains that govern their interactions remains a challenge. Bragg Coh…
