Abstract

Molecular dynamics computer simulations of collision cascades in intermetallic Ni(3)Al, Cu(3)Au and NiAl have been performed to study the nature of the disordering processes in the cascade. The evolution of the crystalline and chemical order parameters show different time scales. To understand these features, the liquid phase of these three alloys is studied and simulation results presented concerning the dynamical melting of small samples, examining the relaxation time and saturation value of the chemical short range order (SRO). A theoretical model for the time evolution of the SRO is given.
