| Popis: | In this work novel routes for consolidating aluminum powders via Equal Channel Angular Pressing (ECAP) are investigated. Furthermore, parameters were optimized for consolidating aluminium reinforced with nanoparticles (n-SiC) and nanofibers (Carbon nanotubes). Consolidating commercial purity aluminum powder with ECAP, approximately 60 % rise in hardness and strength were achieved compared to materials compacted by well established direct extrusion, at the same time losing about 2 times in ductility. Al-1 vol. % nano-SiC composites showed increase in hardness compared to composites consolidated by conventional methods.DOI: http://dx.doi.org/10.5755/j01.ms.18.3.2431 |
