摘要

The article investigates the effect of the shape, distribution, and diameter of graphite inclusions as well as the content of ferrite, pearlite, and carbides in the structure of spheroidal graphite cast iron (SGCI) on its mechanical properties. Nine structural SGCI groups with ferritic, ferritic-pearlitic, and pearlite-ferritic matrices which differ in graphite parameters and the content of pearlite, ferrite, and carbides are analyzed. The cast iron microstructure was studied using optical microscopes and quantitative metallography methods. The mechanical properties were determined in static tensile strength tests. Regression equations were constructed to calculate the tensile strength and elongation values for cast irons with different structures.
