Although poor corrosion resistance is seen as undesirable in many engineering applications, in the area of medical implants, this property enables implanted devices in the human body to corrode and degrade over time.
Figure 3 shows the representative engineering stress-strain curves and tensile properties obtained from the tensile testing of both uncoated and coated samples.

This strength-ductility empiric dilemma has been manifested by the solid solute and dispersion (2 nd -phase particles) hardened alloys which have widespread engineering applications but lower ductility in comparison with their pure metallic matrix.
Mater. 20 (2008) 3028), introducing pre-existing nano-scale growth/deformation twins, engineering 2nd -phase precipitates in a nanostructured matrix, designing multiple-phase alloys or composites, lowering stacking fault energy by alloying, lowering dislocation density and changing grain boundary nature, utilizing phase-transformation plasticity, or deformation under conditions including low temperature or high strain rate (for details, please refer to E.
These strategies have been demonstrated to have varying degrees of success for improving the poor ductility of NS materials, and many of them can satisfy the requirements for engineering application (i.e. uniform elongation before necking is larger than about 5%).
Under such a background, we invited some prominent researchers in this field to contribute regular and review papers on advances in ductility of bulk NS materials to this special topic volume of Materials Science Forum.
