Atomistic simulations of twin facets associated with three-dimensional{1011}twins in magnesium
《Journal of Magnesium and Alloys》2025年第2期626-639,共14页Qiyu Zeng Mingyu Gong Houyu Ma Yao Shen Jian-feng Nie Jian Wang Yue Liu 
supports by the National Key R&D Program of China(No.2022YFB3708900).
Twinning is a deformation mechanism that creates three-dimensional(3D)twin domains through the migration of twin facets.This occurs via the nucleation and glide of twinning disconnections(TDs),which can pile up to cre...

Transmutation of zonal twinning dislocations during non-cozone{1011}twin-twin interaction in magnesium
《Journal of Magnesium and Alloys》2025年第2期681-696,共16页Peng Chen Bin Li 
support from U.S.National Science Foundation(NSF)(CMMI-2016263,2032483).
Theoretically,a twinning dislocation must stay on the twinning plane which is the first invariant plane of a twinning mode,because the glide of twinning dislocation linearly transforms the parent lattice to the twin l...
