Spheroidal cast iron was treated thermomechanically both in high as well as low temperature. The two temperatures we adopted for isothermal quenching were 370° and 300° C. Plastic deformation was obtained by rolling with 25% deformation. Testing was conducted on flat samples used for stretching with the thickness of 4mm. We determined the Rm tensile strength, Rp0,2 proof stress, A elongation, and HRC hardness. A microstructure test (LM, SEM), and X-ray diffraction test were conducted. We found significant positive impact of thermomechanical treatment on the structural characteristics and properties of cast iron, particularly with upper ausferrite present.
