Responses of Pre-transitional Materials with Stress-Generating Defects to External Stimuli: Superelasticity, Supermagnetostriction, Invar and Elinvar Effects
Wei-Feng Rao, Ye-Chuan Xu, John W. Morris +1
We considered a generic case of pre-transitional materials with static stress-generating defects, dislocations and coherent nano-precipitates, at temperatures close but above the s…
Elastically-mediated interactions between grain boundaries and precipitates in two-phase coherent solids
Yechuan Xu, Pierre-Antoine Geslin, Alain Karma
We investigate analytically and numerically the interaction between grain boundaries and second phase precipitates in two-phase coherent solids in the presence of misfit strain. Ou…
Unified Theoretical Framework for Polycrystalline Pattern Evolution
Ari Adland, Yechuan Xu, Alain Karma
The rate of curvature-driven grain growth in polycrystalline materials is well-known to be limited by interface dissipation. We show analytically and by simulations that, for syste…
Distorted magnetic orders and electronic structures of tetragonal FeSe from first-principles
Yong-Feng Li, Li-Fang Zhu, San-Dong Guo +2
We use the state-of-the-arts density-functional-theory method to study various magnetic orders and their effects on the electronic structures of the FeSe. Our calculated results sh…
Two-speed phase dynamics in Si(111) (7x7)-(1x1) phase transition
Ye-Chuan Xu, Bang-Gui Liu
We propose a natural two-speed model for the phase dynamics of Si(111) 77 phase transition to high temperature unreconstructed phase. We formulate the phase dynamics by usi…
Phase-field-crystal modeling of the (2x1)-(1x1) phase-transitions of Si(001) and Ge(001) surfaces
Ye-Chuan Xu, Bang-Gui Liu
We propose a two-dimensional phase-field-crystal model for the (21)-(11) phase transitions of Si(001) and Ge(001) surfaces. The dimerization in the 21 phase…
