Conclusions and Final Remark

The book provides an in-depth understanding of nanostructures and nano-engineering approaches in high strength steels. The state-of-the-art of nanostructures is thoroughly discussed, for instance, nanostructures in metallic materials (ultrafine-grained structure, nano-laminates, nano-plates, nano-particles, nano-precipitates, nano-twins, and gradient nanostructure), the technological processes (thermomechanical treatment, solid reaction, severe plastic deformation), the novel nanostructure characterization methods, the fascinating functional and structural properties, as well as its applications.
