Abstract EN
In this work, we aim to use the Warren-Boettinger model for isothermal solidification to predict the dendritic growth in binary alloys; using the phase field method coupled with a CALPHAD database (CALculation of PHase Diagram).
The main benefit of this work is to study the effect of the excess energy in the phenomena of dendritic growth for the real solution.
We took in consideration, the contribution of the regular solution interaction parameter associated with the excess energy of mixing solid and liquid in the phase field equation phi(x,t) and the concentration equation c(x,t).
The model we proposed is able to simulate the microstructural evolution of the real solution Ni-Cu by linking directly the phase field model to the CALPHAD thermodynamic database.
The comparison of the numerical calculations for the Ni-Cu real solution and the Ni-Cu ideal solution shows that the addition of the excess energy has an important effect on the dendrite form.
