Molecular Dynamics Simulation of the Specific Heat of Undercooled Fe-Ni Melts

In this paper, a molecular dynamics simulation based on the embedded-atom method (EAM) is applied to calculate the specific heat capacity of the Fe-330 Ni alloy at temperatures above and below the melting temperature. The rela- tionship between the specific heat of the alloy and undercooling is investigated. The heat capacity of the Fe-Ni alloy is a constant in the superheated and under- cooled liquid states. Comparisons between previous work and the current study show that the heat capacity behavior of undercooled alloy strongly depends on the species of the alloy.
