Original abstract

The principle of the project is in an analysis of the influence of the cooling rate on structure and mechanical properties. Cooling rate was measured by thermocouples on simple casting with different wall-thickness as well as dendrite arm spacing (DAS) and mechanical properties. Casting were poured into sand moulds and permanent moulds. The influence of the cooling rate on structure and mechanical properties is significant. Values obtained during the experiment will be used for creating material database of Al-alloys for numerical simulation.

Czech abstract

Podstatou výzkumu je analýza vlivu rychlosti ochlazování na strukturu a mechanické vlastnosti slitiny AlSi9Cu3. Rychlost chladnutí byla měřena pomocí termočlánků na odlitcích jednoduchého tvaru s různými tloušťkami stěn, na nichž byla současně měřena hodnota DAS a mechanické vlastnosti. Odlitky byly odlévány do pískových a do kovových forem. Vliv rychlosti chladnutí na strukturu a mechanické vlastnosti je významný. Hodnoty získané při experimentech budou využity do materiálové databáze hliníkových slitin pro numerickou simulaci.
