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.
