Original abstract
Structure of metallic and also majority of ceramic alloys is one of the factors, which significantly influence their physical and mechanical properties. Formation of structure is strongly affected by production technology, casting and solidification of these alloys. Solidification is a critical factor in the materials industry. Solute segregation either on the macro- or micro-scale is sometimes the cause of unacceptable products due to poor mechanical properties of the resulting non-equilibrium phases. Heterogeneity of distribution of components is a function of solubility in solid and liquid phases. Solidification models and simulations have been carried out for both macroscopic and microscopic scales. This chapter presents numerical models of crystallisation of steel, ductile cast iron and ceramics EUCOR aimed at optimisation of their production and properties after casting.
Czech abstract
Struktura kovových a také většiny keramických odlitků je jedním z faktorů, které významně ovlivňují jejich fyzikální a mechanické vlastnosti. Vytváření struktury je značně podmíněno výrobní technologií, odléváním a tuhnutím odlitků. Tuhnutí je zde kritickým faktorem. Segregace v makroskopickém nebo mikroskopickém měřítku je někdy příčinou vzniku nepoužitelných výrobků v důsledku jejich špatných mechnických vlastností. Heterogenita rozložení prvků je funkcí rozpustnosti v tuhé a kapalné fázi. Byl vytvořen model tuhnutí a provedena simulace pro makroskopiské i mikroskopiské měřítko. Předložená kapitola uvádí numerické modely krystalizace oceli, tvárné litiny a keramiky EUCOR, zaměřené na optimalizaci jejich výroby a vlastností po odlití.
