    • A good example here is the excitement generated by the discovery of carbon nanotubes which have exceptionally high strengths better than E/10 (E is Young's modulus, J. Liu, A. G. Rinzler, H. J. Dai, J. H. Hafner, R. K. Bradley, P. J. Boul, A. Lu, T. Iverson, K. Shelimov, C. B. Huffman, F. Rodriguez-Macias, Y. S. Shon, T. R. Lee, D. T. Colbert, R. E. Smalley, Science 1998, 280, 1253).However, it is still uncertain whether such nanotubes can be harnessed into bulk structural materials which can utilize their high strength (and stiffness) without compromising toughness

    • Because of this toughening behavior, Al-Li alloys are used for the main fuel tank of the Space Shuttle. A similar approach of'' delamination toughening'' has recently been used as a means to toughen steels (Y. Kimura, T. Inoue, F. X. Yin, K. Tsuzaki, Science 2008, 320, 1057.).

    • This is the basis of toughening by, transformation-induced plasticity, as for example seen in certain ductile steels that display an in situ martensitic phase transformation; the in situ transformation from the softer austenite to the harder martensite phase provides a steady source of hardening with increasing deformation which acts to delay strain localization. The effect is quite distinct from, transformation toughening, that is found in certain brittle materials, such as zirconia-based ceramics, that undergo also in situ phase transformations
