Abstract

We study the propagation of compact superheated solid in the large undercooling limit using the phase-field model. Below a critical undercooling, the superheated solid decomposes into solid and liquid domains, either in the form of liquid droplets or in periodic structures of concentric rings. For the latter, a one-dimensional analysis provides an excellent estimate for the propagation velocity and for the wavelength. Both numerical and approximate analytical expressions are obtained.
