Laser flash technique has been used to evaluate the thermal conductivity of pear/itk grey cast iron solidified at three distinct cooling rates. Ten different heats were performed with different inoculation treatments. Influences of fraction primary phase and eutectic cell diameter were revealed by colour etching. SEM studies were carried out in order to investigate the graphite morphology of the examined materials. The thermal conditions during solidification as well as the inoculation strongly affect the thermal conductivity of grey cast iron. In general, a more powerful inoculation increases thermal conductivity Small amounts of titanium increase thermal conductivity of grey cast iron considerably. The results show that maximum thermal conductivity is achieved at moderate cooling rates.
