Comprehensive investigations of crystalline systems often require methods bridging
atomistic and continuum scales. In this context, coarse-grained mesoscale approaches are …

Discontinuous plastic flow due to dynamic strain aging (DSA) in a Fe–13Cr–3.4 Mn–0.47 C
metastable stainless steel was studied by uniaxial tensile tests in the temperature range …

Premature failure due to hydrogen has been widely observed in different metallic materials.
How does hydrogen affect the competition between brittle cleavage and ductile fracture is an …

The interface healing mechanism of fine-grained Ni–Co-based superalloy during hot-
compression bonding (HCB) is investigated. During HCB, the incompatibility of deformation …

Solid-solution hardening caused by dissolved hydrogen (H) atoms in face-centered cubic
metals is a favorable phenomenon that counteracts the H-induced degradation of …

The mobility of edge dislocation in Cu–Ni solid solution alloys within a wide range of
temperatures 100–1100 K and Ni concentrations 0–30 at.% is studied by molecular …

Hydrogen is known to embrittle austenitic stainless steels, which are widely used in high-
pressure hydrogen storage and delivery systems, but the mechanisms that lead to such …

Understanding of years-old multifaceted hydrogen-assisted damage evolution necessitates
efforts to model the coupled diffusion-mechanics response in metallic materials. Informed by …

Understanding the interactions between solute atoms and dislocations is essential to
develo** metallic materials for simultaneously high strength and ductility. Previous studies …

We present a new framework to quantify the effect of hydrogen on dislocations using large
scale three-dimensional (3D) discrete dislocation dynamics (DDD) simulations. In this …
