Reversible Modulation of Thermal Conductivity in GaN through Strain-Field Screening around Dislocations
Shantal Adajian, Fanghao Zhang, Andrew Christison +9
Crystalline defects are generally regarded as static phonon scatterers that irreversibly suppress thermal transport. Here we show that elastic strain can reversibly modify dislocat…
Atomistic and data-driven insights into the local slip resistances in random refractory multi-principal element alloys
Wu-Rong Jian, Arjun S. Kulathuvayal, Hanfeng Zhai +5
Refractory multi-principal element alloys (RMPEAs) have attracted growing interest for their exceptional high-temperature strength, yet their complex compositions hinder a mechanis…
Multi-scale Investigation of Chemical Short-Range Order and Dislocation Glide in the MoNbTi and TaNbTi Refractory Multi-Principal Element Alloys
Hui Zheng, Lauren T. W. Fey, Xiang-Guo Li +6
Refractory multi-principal element alloys (RMPEAs) are promising materials for high-temperature structural applications. Here, we investigate the role of chemical short-range order…
Dislocation-induced Y segregation at basal-prismatic interfaces in Mg
Zhifeng Huang, Vladyslav Turlo, Xin Wang +5
Solute segregation at twin boundaries in Mg has been widely investigated, yet this phenomenon has not been studied at the equally important basal-prismatic interfaces. To fill this…
Embracing the chaos: Alloying adds stochasticity to twin embryo growth
Yang Hu, Vladyslav Turlo, Irene J. Beyerlein +4
High-throughput atomistic simulations reveal the unique effect of solute atoms on twin variant selection in Mg-Al alloys. Twin embryos first undergo a stochastic incubation stage w…
A 3D phase field dislocation dynamics model for body-centered cubic crystals
Xiaoyao Peng, Nithin Mathew, Irene J. Beyerlein +2
In this work, we present a 3D Phase Field Dislocation Dynamics (PFDD) model for body-centered cubic (BCC) metals. The model formulation is extended to account for the dependence of…
