Phase discovery with active learning: Application to structural phase transitions in equiatomic NiTi
Jonathan Vandermause, Anders Johansson, Yucong Miao +2
Nickel titanium (NiTi) is a protypical shape-memory alloy used in a range of biomedical and engineering devices, but direct molecular dynamics simulations of the martensitic B19' -…
Ion-Beam Radiation-Induced Eshelby Transformations: The Mean and Variance in Hydrostatic and Shear Residual Stresses
Yongchao Chen, Qing-Jie Li, Alex O'Brien +5
Ion beam plays a pivotal role in ion implantations and the fabrication of nanostructures. However, there lacks a quantitative model to describe the residual stresses associated wit…
Spectral descriptors for bulk metallic glasses based on the thermodynamics of competing crystalline phases
Eric Perim, Dongwoo Lee, Yanhui Liu +8
Metallic glasses have attracted considerable interest in recent years due to their unique combination of superb properties and processability. Predicting bulk metallic glass former…
Predicting Bulk Metallic Glass Forming Ability with the Thermodynamic Density of Competing Crystalline States
Eric Perim, Dongwoo Lee, Yanhui Liu +8
Despite two decades of studies, the formation of metallic glasses, very promising systems for industrial applications, still remains mostly unexplained. This lack of knowledge hind…
Dislocation evolution during plastic deformation: Equations vs. discrete dislocation dynamics study
Kamyar M. Davoudi, Joost J. Vlassak
Equations for dislocation evolution bridge the gap between dislocation properties and continuum descriptions of plastic behavior of crystalline materials. Computer simulations can…
Bauschinger Effect in Thin Metal Films: Discrete Dislocation Dynamics Study
Kamyar M. Davoudi, Lucia Nicola, Joost J. Vlassak
The effects of dislocation climb on plastic deformation during loading and unloading are studied using a two-dimensional discrete dislocation dynamics model. Simulations are perfor…
