We study front instability and the pattern dynamics in the phase-field model with four-fold rotational symmetry. When the undercooling ∆ is 1 < ∆ < ∆ c , the flat interface is linearly unstable, and the deformation of the interface evolves to spatiotemporal chaos or nearly stationary cellular struct
