Chemical short-range order controls deformation pathways in a complex concentrated alloy
Angelo F. Andreoli, Gabriela B. Ribeiro, Guilherme C. Stumpf +12
Chemical short-range order (CSRO) is an intrinsic feature of complex concentrated alloys (CCAs), yet its influence on deformation mechanisms is controversial because of the inconcl…
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
Vinícius 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…
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…
Machine learning potentials for modeling alloys across compositions
Killian Sheriff, Daniel Xiao, Yifan Cao +2
Materials properties depend strongly on chemical composition, i.e., the relative amounts of each chemical element. Changes in composition lead to entirely different chemical arrang…
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…
Chemical-motif characterization of short-range order with E(3)-equivariant graph neural networks
Killian Sheriff, Yifan Cao, Rodrigo Freitas
Crystalline materials have atomic-scale fluctuations in their chemical composition that modulate various mesoscale properties. Establishing chemistry-microstructure relationships i…
Capturing short-range order in high-entropy alloys with machine learning potentials
Yifan Cao, Killian Sheriff, Rodrigo Freitas
Chemical short-range order (SRO) affects the distribution of elements throughout the solid-solution phase of metallic alloys, thereby modifying the background against which microst…
Quantifying chemical short-range order in metallic alloys
Killian Sheriff, Yifan Cao, Tess Smidt +1
Metallic alloys often form phases - known as solid solutions - in which chemical elements are spread out on the same crystal lattice in an almost random manner. The tendency of cer…
