In this paper, we investigate the melting behaviors of Ag17Cu2 and Ag14 metallic clusters, which are generated by an isothermal Brownian-type molecular dynamics simulation with the empirical many-body Gupta potential from low to high temperatures [1,2].The temperature variations in the specific heat of these two clusters exhibit at higher temperature a common main maximum, at which we define as the melting temperature, but at lower temperature they differ by Ag14 having an additional prepeak and none in Ag17Cu2.
