A new phase field method for two-dimensional simulations of binary alloy solidification was studied. A model basing on solute conservative in every unit was developed for solving the solute diffusion equation during solidification. Two-dimensional computations were performed for ideal solutions and Ni-Cu dendritic growth into an isothermal and highly supersaturated liquid phase.

A system for the numerical simulation of 3D
temperature and stress fields during casting process was studied,
developed and practiced based on finite difference method (FDM) in
this paper. An approach where the stress/strain and the heat
transfer analysis use the same computational domain was presented,
which avoided transferring temperature data between FDM and FEM
nodes and elements. A slot-board steel casting was simulated and
the calculated results are in agreements with those obtained from
practical producing.
