Evaluation of Mechanical Properties of Σ5(210)/[001] Tilt Grain Boundary with Self-Interstitial Atoms by Molecular Dynamics Simulation

Figure 4

Shear response of Σ5(210)/[] GBs with various levels of SIA content at 300 K. (a) Snapshots of the bicrystal model with SIA = 0 GBs at = 0 ns and = 6 ns. (b)–(f) Shear stress and the GB position as a function of simulation time with different numbers of SIAs.

(a) SIA = 0 GBs

(b) SIA = 0 GBs

(c) SIA = 5  GBs

(d) SIA = 100 GBs

(e) SIA = 200 GBs

(f) SIA = 300 GBs
