Original abstract
The work is aimed at the field of researching the properties of cast irons with pearlitic structure under different modification degree, and namely within the range from unmodified cast iron up to that one with spheroidal graphite. In dependence on the modification degree and the used modification preparation the cast iron mechanical properties were evaluated and compared, the structure was observed, and chemical composition was analyzed. NiMg6 and FeSiMg6 master alloys were used as modification additives. There was a requirement to produce cast iron from pure raw materials and therefore pig iron forms a main component.
Czech abstract
Práce je zaměřena do oblasti zkoumání vlastností litiny s perlitickou strukturou při různém stupni modifikace, a to v rozmezí od litiny nemodifikované až po litinu s kuličkovým grafitem. V závislosti na stupni modifikace a použitém modifikačním přípravku bylo provedeno vyhodnocení a porovnávání mechanických vlastností litiny, pozorování struktury a rozbor chemického složení. Jako modifikační přísady byly použity předslitiny NiMg6 a FeSiMg6. Požadavkem byla výroba litiny z čistých surovin, a proto hlavní komponentu vsázky tvoří surové železo.
