Softening and hardening of yield stress by hydrogen–solute interactions

William Curtin, Binglun Yin, Ali Tehranchi

Hydrogen atoms have a wide variety of effects on the mechanical performance of metals, and the underlying mechanisms associated with effects on plastic flow and embrittlement remain to be discovered or validated. Here, the reduction in the plastic flow str ...

Mechanisms of hydrogen-enhanced localized plasticity: An atomistic study using alpha-Fe as a model system

William Curtin

Atomistic simulations of the effects of H on edge dislocation mobility and pile-ups are performed to investigate possible nanoscale mechanisms for hydrogen-enhanced localized plasticity (HELP). alpha-Fe is used as a model system because H diffusion is fast ...

Influence of the stress field due to pressurized nanometric He bubbles on the mobility of an edge dislocation in iron

Robin Schäublin, Seyed Masood Hafez Haghighat

Voids and He bubbles are strong obstacles to dislocation, which induce hardening and loss of ductility. In Fe, molecular dynamics simulation is used to investigate the basic mechanisms of the interaction between a moving edge dislocation and a void or He b ...
