Simulation results suggest that twins don’t just facilitate a single mechanism (e.g. ‘detwinning’), but that they facilitate several separate mechanisms simultaneously.
Significance and Impact
Coupled experiment and modeling reveal the dramatic and complex impact of high-density twin boundaries on microstructure evolution and deformation mechanisms
–Cryogenic nanoindentation reveals that high densities of twin boundaries leads to substantial low-temperature grain growth during deformation
–Novel analysis methods applied to LAMMPS MD simulations allow for the detailed quantification of both microstructural evolution and deformation modes as a function of initial structure.
