What is “In Situ” Measurement of Electrical Resistivity, Dilatometry and Thermal Analysis of Cast Iron about?

The contribution describes the "in situ" measurement of electrical resistivity, dilatometry and thermal analyses of flake and spheroidal graphite cast iron in liquid state, during solidification and in solid state. The shape of graphite formed during solidification influences electrical properties and variations of dimensions of cast irons. The complex "in situ" measurements were performed using in house developed measuring cell. The samples were systematically quantitatively metalographically investigated. It was found that electrical resistivity of lamellar grey cast iron is greater than the electrical resistivity of spheroidal graphite cast iron since the lamellas of graphite interrupt the iron matrix more than the nodules and the conduction electrons are scattered more on interfaces between graphite and metal matrix. The electrical resistivity of the flake graphite cast iron is increasing during solidification and decreasing after solidification. Based on "in situ" obtained results of electrical resistivity, dilatations and temperatures the materials properties were reconstructed.
