Investigation of Thermal Diffusivity for the First Generation Graphitic White Iron




Abstract: A new alloy system called graphitic white iron was developed by the authors to improve thermal diffusivity and mitigate over-heating of the wearing surface in the metal-to-metal wear systems. Thermal diffusivity for the first generation graphitic white iron was measured utilizing a laser flash apparatus in accordance with ASTM E1461. Results showed that both the thermal diffusivity and the thermal diffusivity increasing rate increased with increasing graphite volume percent in the alloys developed.
