Možnosti ovlivnění struktury a vlastností odlitků na bázi slitin hliníku

Abstract

This thesis mainly deals with the possibilities of affecting the structure and with properties of aluminum alloy castings mainly based on Al-Si, however marginally affects of aluminum in general. In the experimental part is the work directed primarily towards cooling effects of molds and their influence on the structure. Within the experiments were obtained structural characteristics depending on the method of cooling and the location of structural defects observed in volumes of test samples. Further samples were subjected to the expansion test.
