The role of stacking fault tetrahedra on void swelling in irradiated copper

Irradiation-induced void swelling is known to be higher in metals with an fcc structure compared to bcc, though the reason behind this is unclear. Here, by combining simulations and STEM imaging, stacking fault tetrahedra are found to be the cause of a high swelling rate in fcc copper.

High pressure synthesis of a hexagonal close-packed phase of the high-entropy alloy CrMnFeCoNi

High-entropy alloys represent a new strategy for the design of materials with properties superior to those of conventional alloys, but are largely limited to simple phases of cubic symmetry. By applying high pressures on CrMnFeCoNi, here authors demonstrate synthesis of a hexagonal close-packed phase.

Improving atomic displacement and replacement calculations with physically realistic damage models

The Norgett−Robinson−Torrens displacements per atom model is the benchmark to assess radiation damage in metals but has well-known limitations. Here, the authors use molecular dynamics to introduce material-specific modifications to describe radiation damage more realistically.
