The comparative studies of the alloy were performed using differential scanning calorimetry, dilatometry and laser flash analysis. The calorimetric investigations proved that upon the heating to melting temperature (~1200°C), four endothermic transformations take place: Keywords: vermicular cast iron, thermophysical properties, transformation temperatures, melting heat, thermal expansion, thermal expansion coefficient, thermal diffusivity, thermal conductivity, Download 3.85 MB >> |
