Chemical short-range order controls deformation pathways in a complex concentrated alloy
Angelo F. Andreoli, Gabriela B. Ribeiro, Guilherme C. Stumpf +12
The study experimentally demonstrates that chemical short-range order (CSRO) in a Co‑Cr‑Ni complex concentrated alloy modifies stacking‑fault energies and suppresses deformation‑in…
Complementary Thermodynamic Mechanisms of Boron and Carbon Segregation at Grain Boundaries in Nickel Alloys
Tyler D. Doležal, Rodrigo Freitas, Ju Li
Grain boundary stabilization by light interstitials is central to the performance of Ni-based superalloys, yet the thermodynamic mechanisms governing their interactions with substi…
Direct Observation of Chemical Short-Range Order in CoCrNi Alloy Using Neutron Diffraction
VinÃcius P. Bacurau, Camilo Salvador, Guilherme C. Stumpfa +8
This study provides experimental evidence of chemical short-range order (CSRO) in the equiatomic CoCrNi alloy, identified through neutron diffraction. The phenomenon manifests as a…
Nonequilibrium chemical short-range order in metallic alloys
Mahmudul Islam, Killian Sheriff, Yifan Cao +1
Metallic alloys are routinely subjected to nonequilibrium processes during manufacturing, such as rapid solidification and thermomechanical processing. It has been suggested in the…
Atomistic Simulations of Short-range Ordering with Light Interstitials in Inconel Superalloys
Tyler D. Dolžal, Emre Tekoglu, Jong-Soo Bae +3
This study employed hybrid Monte Carlo Molecular Dynamics simulations to investigate the short-range ordering behavior of Ni-based superalloys doped with boron or carbon. The simul…
Segregation and Ordering of Light Interstitials (B, C, H, and N) in Cr-Ni Alloys: Implications for Grain Boundary Stability in Superalloy Design
Tyler D. Doležal, Rodrigo Freitas, Ju Li
The segregation and ordering behavior of light interstitials (B, C, and N) in Cr30-Ni is examined, as these elements are critical for grain boundary stability and high-temperature…
