Sažetak
The microstructure, tensile properties and hardness of 25 mm thick compacted graphite iron samples alloyed with 3, 01, 3, 22, 3, 61, 3, 97 and 4, 29 wt. % Si were analyzed in this paper. It was found that Si promotes and strengthens ferrite. Metallic matrix of compacted graphite iron sample alloyed fully ferritic metallic matrix was obtained in compacted graphite iron samples and nodularity. Yield strength increased, tensile strength increased, hardness increased, and elongation decreased with an increase in Si content from 3, 01 to 4, 29 wt. %. Analyzed Si alloyed compacted graphite iron samples have a very uniform hardness and higher ratio Rp0, 2/Rm than conventional ferritic, ferritic-pearlitic and pearlitic compacted graphite iron grades.
