Fig. 5From: Methods to evaluate the twin formation energy: comparative studies of the atomic simulations and in-situ TEM tensile testsa Representative TEM image of the tensile-test < 110> Al NW, showing the formation of four twins with a zig-zag configuration. b Magnified view of the twinned region showing the interlocking configuration of the twins. c Stress-strain curve of the Al NW recorded by unloading the sample. Note that the Al NW was observed to yield with the formation of twins at σ= 2.3 GPa (equivalently, at ε = 3.4%)Back to article page
