Influence of the rate of cooling on the formation of non-equilibrium eutectics in preeutectic alloys of the AL-SI system

  • 1 National Technical University of Ukraine "Kyiv Polytechnic Institute named after Igor Sikorskyi" - Kyiv, Ukraine


Computer experiments were carried out with a simulation model of alloy crystallization in this work. The model was preliminarily calibrated for alloys of the Al-Si system. The presence of a non-equilibrium eutectic in pre-eutectic alloys with a silicon content of 1.0% – 1.6% has been detected. The minimum cooling rates at which the formation of an eutectic in these alloys is possible have been determined.
