✦ Synopsis

The kinetics of dendritic solidification in undercooled Ni-Zr samples is analyzed using new experimental results and theoretical studies based on a sharp-interface model and phase-field simulations. The predictions of a sharp-interface model and of a diffuse-interface model describing the phase transition considering both thermal and solutal diffusion are compared with the new experimental results by evaluating the dendritic tip velocity in electromagnetically levitated Ni-Zr samples.
