Abstract

A finite element model for the solidification of molten metals and alloys in cylindrical molds is developed using the energy equation in terms of temperature and enthalpy. TheNewton-Raphson technique was used to solve the resulting nonlinear algebraic equations. A computer program is developed to calculate the enthalpy, temperature, and fraction solid per the classical Lever rule, Scheile equation, and Brody-Flemings models. Cooling curves are calculated for pure metal (aluminum), two eutectic alloys (Al-33.2 pct Cu and Al-12.6 pct Si), and three hypoeutectic alloys (Al-2.2 pct Cu, Al-4.5 pct Cu and Al-7 pct Si) and are compared with the experimental curves.
