A Molecular Dynamics Simulation Study of the Cavitation Pressure in Liquid Al

To understand the formation mechanism of hot tearing defects generated during casting, a knowledge of the pressure at which cavities form spontaneously in the liquid metal is required. In this work, molecular dynamics (MD) simulations were used to compute the cavitation pressure Pc in liquid Al, where atomic interactions were described by an embedded atom method potential. The cavitation pressure was computed for various initial conditions and …
