  Kinetics of crystal-growth is investigated along the solid-liquid coexistence
line for the (100), (110) and (111) orientations of the Lennard-Jones and
Weeks-Chandler-Andersen fcc crystal-liquid interface, using non-equilibrium
molecular dynamics simulations. A slowing down of the growth kinetics along the
coexistence line is observed, which is mostly a temperature effect, with other
quantities such as the melting pressure and liquid self-diffusion coefficient
having a negligible impact. The growth kinetics of the two potentials become
similar at large values of the melting temperature and pressure, when both
resemble a purely repulsive soft-sphere potential. Classical models of
crystallization from the melt are in reasonable qualitative agreement with our
simulation data. Finally, several one-phase empirical melting/freezing rules
are studied with respect to their validity along the coexistence line.
