摘要：
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-33% Ni alloy at temperatures above and below the melting temperature. The relationship between the specific heat of the alloy and undercooling is investigated. The heat capacity of the Fc-Ni alloy is a constant in the superheated and undercooled 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.
