The mechanisms of dislocation/precipitate interactions were analyzed in an Al–Cu alloy
containing a homogeneous dispersion of θ′ precipitates by means of discrete dislocation …

A novel dislocation-density-based crystal plasticity model for nanocrystalline face-centered
cubic metals is developed based on the thermally-activated mechanism of dislocations …

The interaction between edge dislocations and Guinier-Preston zones in an Al-Cu alloy was
analyzed by means of atomistic simulations. The different thermodynamic functions that …

Predicting the effects of microstructure on high-temperature creep responses of steel
components is critical to minimize the risks of failure and maximize economic viability in the …

The influence of the stress state on the cross-slip rate in Al was analyzed by means of
molecular dynamics simulations and transition state theory. The activation energy barrier in …

In part 1, we formally defined important physical concepts in statistical thermodynamics that
undergird internal state variable (ISV) theory such as configurational subsystems (eg …

Cross-slip of screw dislocations in crystalline solids is a stress-driven thermally activated
process essential to many phenomena during plastic deformation, including dislocation …

The mechanical responses of hexagonal close-packed (HCP) materials are highly
anisotropic, as well as strain rate and temperature-dependent, because of inherently …

Equilibrium fluctuations of dislocations are central to the plastic response of metals and
alloys because they control the attempt frequency of thermally activated events. We analyze …

This three-part paper lends new insight into the interpretation of internal state variable (ISV)
theory and fundamentals of the behavior of thermally activated dislocation ensembles. We …
