A Thermal Conductivity Model for Grey Iron

Abstract Thermal conductivity is an important property for many iron cast components, and the lack of widely accepted thermal model iron, especially grey motivates efforts in this research area. The present study contributes to understanding effects alloy microstructure has on conductivity. A a pearlitic been proposed, based as-cast composition microstructural parameters obtained at different solidification rates. According model, available parallel heat transfer paths formed by connected graphite flakes across eutectic cells are determined space between dendrite arms. uncertainties both inputs validation measurements have estimated. Sensitivity analysis conducted result better behaviour. agreement modelled measured conductivities achieved within 5% average investigated samples.
