Computation of liquid Cu70Ni30 alloy structure using EAM in rapid cooling and heating process

A series of simulations of the glass transition of Cu70Ni30 alloy have been carried out based on the molecular dynamics simulation technique under constant temperature and constant pressure. Atoms interact via semi-empirical many-body potential EAM. The pair correlation function, pair analysis technique and bond orientation order parameters are used to reveal the structural features of Cu70Ni30 alloy in a state of liquid, super cooled liquid and glass as well as structural evolution in the process of the rapid solidification. In the quick heating of the amorphous metal obtained by the quick cooling method, the ordering degree of the system is kept, to some extent, to the next stage. (C) 1999 Elsevier Science S.A.
