Fecha de publicación: | ago-2009 | Editor: | Elsevier | Citación: | Scripta Materialia 61 (4) : 407-410 (2009) | Resumen: | A multilayer aluminium laminate comprising ten layers of Al-Zn-Mg-Cu alloy (82 vol.%) and nine layers of pure aluminium (18 vol.%) has been processed by hot rolling. The rolled laminate was characterized by electron backscattering diffraction, Charpy impact and shear tests. The multilayer laminate showed an outstanding Charpy impact toughness, being eighteen times higher than that for the as-received Al-Zn-Mg-Cu alloy. Damage tolerance improvement was due to the high volume fraction of the high strength aluminium and extrinsic fracture mechanisms. | Versión del editor: | http://dx.doi.org/10.1016/j.scriptamat.2009.04.030 | URI: | http://hdl.handle.net/10261/43696 | DOI: | 10.1016/j.scriptamat.2009.04.030 | ISSN: | 1359-6462 |
