Abstract: Spheroidal graphite cast irons are versatile materials that have multiple property combinations. In this study, various amounts of silicon alloys and ferrite were added to samples of spheroidal graphite cast iron to determine how this would affect their thermal conductivities. A Hot Disk TPS 2500 S was used to measure the thermal conductivities of the composites with the transient plane source (TPS) method from room temperature to 400 °C. Results showed that the thermal conductivity of the cast iron alloys decreased with increasing concentrations of silicon and pearlite, however thermal conductivity increased with rising temperature.
