Abstract

High temperature thermophysical properties of Fe and Fe alloys with small additions of C and Mn are reported using electrostatic levitation, for the first time. Thermophysical property measurements were carried out in wide temperature ranges from 800 K to 1850 K, including solids, supercooled, and stable liquids. The small additions of C and Mn affect transformation temperatures, but not significantly other thermophysical properties, i.e., density, volume expansion coefficient, and specific heat. Anomalous volume expansion coefficient was observed in δ-phase.
