| Description
| - Influence of repeated using of alloys on base Al – Cu is the goal of this study. Alloy RR350 was used for this study. Specimens for tension examination were casted to the metal forms, which were protected by preservative coating. Pouring temperature and temperature of iron mold were controlled in order to keep constant conditions of experiments for all testing samples. From poured samples the testing rods were prepared to determination of tensile strength under laboratory (20 °C) and under higher temperature (with maximum about 350 °C). Specimens were also taken for determination of hardness (HBS) and metallographic analysis from poured samples. Metaloographic analysis was evaluated by using microscope GX 51, which equips polarization light with magnification from 12.5 to 1000. Thermo-mechanical properties were carried out at the author´s working place – Department of Foundry Engineering, Faculty of Metallurgy and Material Engineriing, Technical University of Ostrava. Description of this measurement methodology and metallographic analysis of microstructures are also part of this contribution. At the experimental part of this study hardness of experimental samples, which were prepared at different melts with further determination of chemical composition by spectral method analysis, are evaluated. The results of this study definite confirmed negative influence of repeated using studied alloy on thermo-mechanical and structure properties. At the conclusion of this study there are also described possibilities of further treatment and machining of studied material (inoculation and further precipitation hardening). (en)
