Dislocation Behavior in TiVTa Multi-Principal Element Alloys: A Nanoindentation Simulation Study

Crystals
Molecular dynamics simulations of nanoindentation were conducted to compare the dislocation behavior in a pure V and a TiVTa multi-principal element alloy (MPEA) with [100] and [111] crystal orientations.

Low-dose damage evolution in pure magnesium under electron irradiation: Effect of foil orientation and pre-existing dislocations

Nuclear Materials and Energy
Low-dose damage evolution in commercial purity (99.95 wt%) magnesium has been investigated, under 200 keV electron irradiation at room temperature, up to ∼0.03 displacements per atom.

Unveiling the inhibitory effect of hydrogen-decorated voids and dislocation loops on the glide of edge dislocation in tungsten

Nuclear Fusion
Tungsten (W), as the most promising candidate for plasma-facing materials, will experience significant irradiation hardening in nuclear fusion environment, which is originated from the formation of displacement damages, such as voids and dislocation ...
