The structure and migration of twin boundaries in tetragonal -Sn: an application of machine learning based interatomic potentials
Ian Chesser, Mashroor Nitol, Esther C. Hessong +7
Although atomistic simulations have contributed significantly to our understanding of twin boundary structure and migration in metals and alloys with hexagonal close packed (HCP) c…
Exploring the relation between transonic dislocation glide and stacking fault width in FCC metals
Kathryn R. Jones, Khanh Dang, Daniel N. Blaschke +2
Theory predicts limiting gliding velocities that dislocations cannot overcome. Computational and recent experiments have shown that these limiting velocities are soft barriers and…
The structure and migration of heavily irradiated grain boundaries and dislocations in Ni in the athermal limit
Ian Chesser, Peter M. Derlet, Avanish Mishra +6
The microstructural evolution at and near pre-existing grain boundaries (GBs) and dislocations in materials under high radiation doses is still poorly understood. In this work, we…
Properties of accelerating edge dislocations in arbitrary slip systems with reflection symmetry
Daniel N. Blaschke, Khanh Dang, Saryu Fensin +1
We discuss the theoretical solution to the differential equations governing accelerating edge dislocations in anisotropic crystals. This is an important prerequisite to understandi…
Limiting velocities and transonic dislocations in Mg
Khanh Dang, Daniel N. Blaschke, Saryu Fensin +1
To accurately predict the mechanical response of materials, especially at high strain rates, it is important to account for dislocation velocities in these regimes. Under these ext…
