Abstract

This thesis deals with spheroidal graphite cast iron with an increased amount of silicon intended for heavy castings. For this purpose, test blocks were cast from materials quality EN-GJS-450-18 and EN-GJS-500-14 with the dimensions 300 x 300 x 500 mm. It was examined the effect of silicon on mechanical properties and the microstructure of these quality grades of cast iron.
