Atomistic study of internal stress effect on scratching behavior in titanium single crystal
Journal of Materials Research and Technology, 2023 The internal stress effect on the scratching behavior in titanium single crystal is investigated by molecular dynamics simulations. It is introduced by applying the compressive/tensile pre-strain in this work.

The collapse of defect cascades to dislocation loops [PDF]
Journal of Nuclear Materials, 1987 We describe a number of experiments that we have recently performed to investigate the collapse of defect cascades to dislocation loops. This important ion and neutron irradiation phenomenon has been studied with in situ ion bombardment using the High Voltage Electron Microscope-Ion Accelerator Facility at Argonne National Laboratory in Cu3Au, Cu, and ...

Interrelation between Dislocation Loops and an Edge Dislocation
MATERIALS TRANSACTIONS, 2005 Since it has recently become an important subject to study the interrelation between a dislocation loop and a straight edge dislocation because of dynamic behaviors of small dislocation loops under irradiation condition, the simulation studies were made in model Fe lattice.
