| Description
| - Byl studován vliv technologického postupu výroby na mikrostrukturu, texturu, mechanické a technologické vlastnosti dvou slitin - AlMg2Mn0.8 (AA5049) a AlMg3 (AA5754) - komerčně vyráběných plynulým litím mezi válce. Plechy o finální tloušťce 1.0 mm byly připraveny v laboratorních podmínkách, s homogenizací a bez homogenizace. Kromě toho byly nehomogenizované vzorky válcovány většími úběry v průmyslových podmínkách. Překvapivě bylo zjištěno, že homogenizace vede ke zhrubnutí zrna a k degradaci anizotropie materiálů. Plechy připravené nejjednodušším postupem válcováním za studena z licí tloušťky 6.0 mm přímo na finální tloušťku 1.0 mm s následným žíháním na měkký stav vykazují velmi jemné zrno, vyšší mechanické charakteristiky, vyšší tažnost a nižší anizotropii než plechy homogenizované na tloušťce 4 mm. Struktura a mechanické vlastnosti materiálů připravených v laboratorních a v průmyslových podmínkách je trochu odlišná. (cs)
- The influence of specific processing routes on the microstructure, texture, mechanical and technological properties of two commercial twin-roll cast alloys - AlMg2Mn0.8 (AA5049) and AlMg3 (AA5754) - was investigated. Sheets of 1.0 mm gauge were prepared in laboratory conditions with and without homogenization treatment. Non-homogenized samples were rolled also in industrial conditions. Surprisingly, it was found that homogenization results in grain coarsening and degradation of sheet anisotropy. Sheets produced by cold rolling from as-cast thickness of 6.0 mm directly to thickness of 1.0 mm and final annealing exhibit very fine grain size, higher strength combined with higher elongation and lower anisotropy as compared to the homogenized variant. The structure and mechanical properties of materials processed in laboratory and in industrial conditions are slightly different.
