Figure 3: Surface morphologies and dislocation arrangements of the bicrystals with an inclined TB.
From: Controllable fatigue cracking mechanisms of copper bicrystals with a coherent twin boundary
(a) Slip morphologies with fatigue cracks (scale bar, 20 μm) and (b) the dislocation arrangement of the bicrystal with a TB inclined at 45° (scale bar, 5 μm). (c) Slip morphologies with fatigue cracks (scale bar, 10 μm) and (d) the dislocation arrangement of the bicrystal with a TB inclined at 30° (scale bar, 5 μm). (e) Slip morphologies with fatigue cracks (scale bar, 20 μm) and (f) the dislocation arrangement of the bicrystal with a TB inclined at 60° (scale bar, 5 μm).
