DOI: 10.1007/s12540-019-00475-0
Abstract: Cyclic plastic deformation behavior of nanocrystalline body-centered cubic (BCC) iron is investigated using molecular dynamics simulation. The formation of X-junction and Y-junction during deformation causes the faster mobility of dislocation, which results in softening behavior… read more here.

Dynamics of interaction between dislocations and point defects in bcc iron
Sign Up to like & getrecommendations! Published in 2018 at "Physical Review Materials"
DOI: 10.1103/physrevmaterials.2.103604
Abstract: The interaction between dislocations and point defects is crucial for many physical properties and phenomena in materials, such as strengthening mechanisms, dislocation bias and void swelling, creep, and impurity segregation around dislocations. Conventional dislocation-point defect… read more here.
