Abstract
A pure numerical method is proposed for solving the solidification temperature, solid fraction, and liquid composition correlation (T-fs-CL) in strongly coupled binary solidification problems. The method accommodates both single-phase and eutectic solidification processes and eliminates the need to assume any specified function for the local T-fs-CL relationship or the linearizations of the liquidus and solidus for a given alloy. A sample calculation performed with an Al-4.5%Cu alloy, a hypoeutectic system, illustrates the feasibility of the established numerical method. Further discussion shows that the proposed numerical solution to the T-fs-CL coupling will also be suitable for local remelting simulations.
