The contribution deals with comparison of microstructure, mechanical properties and fatigue properties of synthetic nodular cast irons with a different ratio of steel scrap in a charge. Chemical composition of individual melts was regulated alternatively by ferrosilicon (FeSi) and carburizer or metallurgical silicon carbide (SiC). The paper shows positive influence of SiC additive on the microstructure, mechanical properties as well as fatigue properties of nodular cast iron. The additive of metallurgical silicon carbide in analysed specimens increases the content of ferrite in the matrix, decreases the size of graphite and increases the average count of graphitic nodules per unit of area. Consequently, the mechanical and fatigue properties of nodular cast iron are improved.

A Charge

The contribution deals with comparison of microstructure, mechanical properties and fatigue properties of synthetic nodular cast irons with a different ratio of steel scrap in a charge. Chemical composition of individual meltages was regulated alternatively by ferrosilicon (FeSi) and carburizer or metallurgical silicon carbide (SiC). The paper shows that SiC additive positively influences the microstructure, mechanical properties as well as fatigue properties of nodular cast iron, especially in the meltages with higher ratio of steel scrap in the charge. Moreover, production of synthetic nodular cast irons with SiC additive is economically advantageous.
