Atomistic simulations of energies for arbitrary grain boundaries. Part II: Statistical analysis of energies for tilt and twist grain boundaries
TL;DR: In this article, the orientation-dependency of grain boundary (GB) energy in Al is investigated using a cutoff sphere molecular dynamics model presented in Part I, which is applicable to arbitrary GBs.

Atomistic simulations of energies for arbitrary grain boundaries. Part I: Model and validation
TL;DR: In this article, a cutoff sphere molecular dynamics model is proposed to calculate the energies of arbitrary grain boundary (GB)s, which eliminates the effect of interaction between free surface and GB in a bicrystal cell by excluding the surface region in the energy computation.

On the selection of outlet channel length and billet length in equal channel angular extrusion
TL;DR: In this paper, the deformation behavior during equal channel angular extrusion (ECAE) of a typical strain hardening material with different combinations of outlet channel length and billet length is simulated using the finite element method.
