摘要

The specific heat of liquid Fe90Si6.95Sn3.05 alloy has been investigated by electromagnetic levitation drop calorimetery in the temperature range of 1390-2140 K. The enthalpy of this liquid alloy increases linearly with the rise of temperature. Furthermore, the enthalpy obtained from molecular dynamics calculation shows a similar trend to the experimental results in a broader temperature range of 1000-2200 K. The calculated specific heat is 39.7 J mol-1 K-1, which agrees well with the experimental result of 39.9 J mol-1 K-1. The density of this liquid alloy decreases as a quadratic function of temperature.
