EN The influence of a shape of graphite precipitates in cast iron on the thermal shock resistance of the alloy was initially determined. Investigations included the nodular cast iron and the vermicular one, as well as the cast iron containing flake graphite. The thermal shock resistance was examined at[...]

EN The influence of aluminium (added in quantity from about 0.6% to about 2.8%) on both the alloy matrix and the shape of graphite precipitates in cast iron treated with a fixed amounts of cerium mischmetal (0.11%) and ferrosilicon (1.29%) is discussed in the paper. The metallographic examinations were[...]

EN The influence of aluminium added in amounts of about 1.6%, 2.1%, or 2.8% on the effectiveness of cast iron spheroidization with magnesium was determined. The cast iron was melted and treated with FeSiMg7 master alloy under industrial conditions. The metallographic examinations were performed for the[...]

EN The performed investigations have resulted in conclusion that the vermicularizing treatment of 'basic' cast iron, consisting in 'conditioning' the alloy by means of VLCe(2) master alloy, introducing the DENODUL5 master alloy, and graphitizing with SRF75 master alloy, provides for obtaining vermicula[...]

EN The work determined the influence of aluminium in the amount from about 1% to about 7% on the graphite precipitates in cast iron with relatively high silicon content (3.4% to 3.90%) and low manganese content (about 0.1%). The cast iron was spheroidized with cerium mixture and graphitized with ferros[...]

EN The paper discusses the influence of aluminium in quantities from about 1.9% to about 4.7% on both the alloy matrix and the shape of graphite precipitates in cast iron spheroidized with cerium mixture (added in the quantity of 0.11%) and inoculated with ferrosilicon (1.29%). The metallographic exami[...]

PL W artykule omówiono wyniki badań nad wpływem małych dodatków bizmutu (od 0,0006% do 0,0017%) i ceru (od 0,010% do 0,043%), wprowadzonych jako modyfikatory do żeliwa nadeutektycznego (Sc od 1,02 do 1,09), na charakterystyki grafitu oraz udział ferrytu w osnowie. Stwierdzono, że następuje zmniejszenie[...]
EN The paper discusses results of investigation concerning the influence of small additions of bismuth (from 0,0006% to 0,0017%) and cerium (from 0,010% to 0,043%) introduced as modifiers into the hypereutectic cast iron (Sc from 1,02 to 1,09) on the graphite characteristics and the fraction of ferrite[...]

EN The work presents results of investigations concerning the production of cast iron containing about 5-6% aluminium, with the ferritic matrix in the as-cast state and nodular or vermicular graphite precipitates. The examined cast iron came from six melts produced under the laboratory conditions. It c[...]
