Single crystal Ni-based superalloys have long been an essential material for gas turbines in
aero engines and power plants due to their outstanding high temperature creep, fatigue and …

The phase-field dislocation dynamics (PFDD) method, originated in 2002, is a continuum
dislocation model that uses order parameters to describe dislocation slips in crystalline …

Grain boundaries (GBs) in polycrystalline materials act as impediments to dislocation motion
and result in strengthening. Understanding slip transmission through GBs, specifically twin …

In this review article, we present and discuss recent mesoscale modeling studies of slip
transmission of dislocations through biphase interfaces. Specific focus is given to fcc/fcc …

Dislocation-precipitate interaction and solute segregation play important roles in controlling
the mechanical behavior of Ni-based superalloys at high temperature. In particular, the …

Many elementary deformation processes in metals involve the motion of dislocations. The
planes of glide and specific processes dislocations prefer depend heavily on their atomic …

The effects of hydrogen on dislocation mobility and operation of the Frank-Read source are
evaluated using our recently developed phase-field model. This is achieved by accounting …

Mixed-type dislocations are prevalent in metals and play an important role in their plastic
deformation. Key characteristics of mixed-type dislocations cannot simply be extrapolated …

In this work, a kinetic Monte Carlo (KMC) scheme is integrated into a phase field dislocation
dynamics (PFDD) model to account for thermal activation. While the implementation is …

The purpose of this work is the development of a framework for the formulation of
geometrically non-linear inelastic chemomechanical models for a mixture of multiple …
