Numerical simulation of solidification for aluminum-base multicomponent alloy

摘要: Solidification simulation of an aluminum-base multicomponent alloy was carried out by a method combining thermodynamic analysis using Thermo-Calc and heat-transfer calculation. An Al-9.5% Si-3% Cu-1% Mg-0.8% Fe (all mass%) used for the simulation. The effect latent heat on calculation considered enthalpy method. temperature-enthalpy curves both equilibrium state nonequilibrium with assumptions no diffusion in solid were calculated Thermo-Calc. A small casting cylindrical shape vertical cross section divided into rectangular grids, change each grid numerically calculated. enthalpies grids converted time-step temperatures curve. experiment under same conditions as those simulation, cooling obtained condition agreed experimental ones.
