Local chemical order suppresses grain boundary migration under irradiation in CrCoNi
Ian Geiger, Penghui Cao, Timothy J. Rupert
Complex concentrated alloys with intrinsic chemical heterogeneity are promising candidates for nuclear applications, where local chemical order can strongly influence defect evolut…
Grain boundaries amplify local chemical ordering in complex concentrated alloys
Ian Geiger, Yuan Tian, Ying Han +4
Local chemical ordering strongly influences the behavior of complex concentrated alloys, yet its characterization remains challenging due to the nanoscale dimensions and scattered…
A simple model for short-range ordering kinetics in multi-principal element alloys
Anas Abu-Odeh, Bin Xing, Penghui Cao +2
Short-range ordering (SRO) in multi-principal element alloys influences material properties such as strength and corrosion. While some degree of SRO is expected at equilibrium, pre…
Atomic-scale tunable phonon transport at tailored grain boundaries and Their Impact on Thermal Conductivity
Xiaowang Wang, Chaitanya A. Gadre, Wanjuan Zou +16
Grain boundaries (GBs) strongly influence thermal transport in crystalline solids by disrupting lattice periodicity and scattering phonons. Due to the atomic-level disorder and str…
A Machine Learning Framework for the Prediction of Grain Boundary Segregation in Chemically Complex Environments
Doruk Aksoy, Jian Luo, Penghui Cao +1
The discovery of complex concentrated alloys has unveiled materials with diverse atomic environments, prompting the exploration of solute segregation beyond dilute alloys. Data-dri…
Frustrated metastable-to-equilibrium grain boundary structural transition in NbMoTaW due to segregation and chemical complexity
Ian Geiger, Diran Apelian, Xiaoqing Pan +3
Grain boundary structural transitions can lead to significant changes in the properties and performance of materials. In multi-principal element alloys, understanding these transit…
