| dc.description.abstract | The contribution is aimed at study of influence of chemical composition of compacted graphite cast iron (CGI)
on microstructure and surface quality of castings, particularly on the occurrence of pinholes. It has been found
out that aluminium and titanium in CGI effect the formation of this defect in castings. Aluminium content in
the range of 0,02 up to 0,1 % is critical. Increased occurrence of pinholes was also determined with Ti contents
above 0,1%. On the same set of experimental castings it has been found out that increased contents of those
elements on the other hand support the crystallization of compacted graphite. But the utilization of that method
for control of CGI microstructure is limited with a possibility of formation of surface defects in castings –
pinholes, but also coldshuts and shrinkage cavities. | en |

mikrostrukturu i površinska svojstva, osobito pri pojavi poroznosti. Utvrden je utjecaj aluminija i titana na
nastanak pora u odljevcima. Kritičan je udio aluminija izmedu 0,02 i 0,1%. Takoder, pore su učestalije pri udjelu
titana iznad 0,1%. Na istim uzorcima eksperimentalnih odljevaka utvrdeno je i kako povišeni udjeli ovih elemenata
istodobno potpomažu kristalizaciju vermikulanog grafita. Primjena metode za kontrolu mikrostrukture
odljevaka s vermikularnim grafitom (CGI) limitirana je, uz mogućnost pojave površinskih nedostataka odljevaka
u vidu pora, hladnih zavara i šupljina nastalih skupljanjem. | en |
