Original abstract
The research examined the influence of different kinds of graphite inoculants when casting nodular cast iron on the structure and mechanical properties of the castings. The test alloy was a nodular cast iron corresponding with the ČSN EN GJS 450 standard. The modification was done with a VM 63M alloy by a Sandwich method. A comparison was made of the inoculating effects of 3 sorts of inoculants applied by a single-stage modification. Test moulds samples of Y1-Y4 type complying with the ČSN EN 1563 standard were cast. These samples were tested for their mechanical properties using the tensile, hardness and impact tests. A metallographic evaluation of the graphite and basic metal structure was made for all the samples.

Výzkum zkoumal vliv různých druhů očkovadel při odlévání litiny s kuličkovým grafitem na její strukturu a mechanické vlastnosti odlitků. Zkušební slitinou byla litina s kuličkovým grafitem odpovídající normě ČSN EN GJS 450. Modifikace byla provedena pomocí slitiny VM 63M sendvičovou metodou. Bylo provedeno srovnání očkovacích účinků 3 druhů očkovacích látek aplikovaných jednostupňovou modifikací. Byly odlity vzorky zkušebních forem typu Y1-Y4 vyhovující normě ČSN EN 1563. Tyto vzorky byly testovány na své mechanické vlastnosti pomocí zkoušek tahem, tvrdostí a rázem. U všech vzorků bylo provedeno metalografické hodnocení grafitu a základní kovové struktury.
