Original abstract

In the article there are concentrated and partly commented the results of tensile and fatigue tests which were realised on the alloys EN-AW 6082/T6 and alloy EN-AW 7075/T6. Semi products of these materials were produced by extruding technology and their structure demonstrated visually inhomogeneity (directionality). In the frame of experimental tests they were evaluated and mutually compared the mechanical parameters obtained on the samples produced in different directions to the extrusion axis. The reached results indicate that the fatigue properties of tested materials are influenced by the structure orientation only gently.

Czech abstract

V článku jsou soustředěny a částečně komentovány výsledky tahových a únavových zkoušek, které byly realizovány na Al slitinách EN-AW 6082/T6 a EN-AW 7075/T6. Polotovary těchto materiálů byly vyrobeny technologií protlačování a jejich struktura vizuálně vykazuje významnou nehomogenitu (směrovost). V rámci experimentálních prací byly hodnoceny a vzájemně porovnány mechanické parametry získané na vzorcích, vyrobených v různých směrech vzhledem k ose protlačování. Dosažené výsledky naznačují, že únavové vlastnosti sledovaných materiálů jsou směrovostí struktury ovlivněny pouze mírně.
