A molecular dynamics simulation study of semi-solid-state Fe: high temperature elasticity and void formation in liquid

Abstract: -Hot tearing defects appear during the last steps of casting solidification of dendrites. The crystalline structure traps a small amount of liquid metal, which is depressed, and cavities are spontaneously initiated. Molecular dynamics (MD) simulations of pure iron are able to predict, on one hand, the high temperature elastic modulus of crystals, and on the other hand, the cavitation event in liquid metal and near the solid-liquid growth front. High values of elastic tensor components are predicted close to th… Show more
