• (Figure 9). An abrupt elastic-to-plastic transition was not observed even for bending curvatures up to 90°. A hard coating may prevent stress release mechanisms related to dislocation pile up and dislocation nucleation at the surface [33][34]. However, more systematic studies on the role of coating need
