Influences of the Graphite Growth Direction on the Thermal Conductivity of Cast Iron
|
The thermal conductivity of ferritic spheroidal graphite iron samples containing various amounts of chunky or spheroidal graphite was investigated by means of the laser flash method. Scanning electron microscopy studies were performed to investigate the graphite morphology. Although chunky graphite is believed to grow in large interconnected eutectic cells, no beneficial effects on the thermal transport properties can be established for spheroidal graphite irons containing considerable amount...
