The establishment of solute boundary layer is studied by using a quantitative phase field model during the initial transient stage of binary alloys solidification. Results reveal that the time-dependent solute distribution shows good agreements with the previous analytical results. The planar instability is discussed according to the time-dependent constitutional supercooling with different pulling velocities. Moreover, the critical pulling velocity of planar instability can be obtained by investigating the interface velocity of the critical instability with different pulling velocities. © 2010 World Scientific Publishing Company.
