  The dynamics of homogeneous nucleation and growth of crystalline nickel from
the super-cooled melt is examined during rapid quenching using molecular
dynamics and a modified embedded atom method potential. The character of the
critical nuclei of the crystallization transition is examined using common
neighbor analysis and visualization. At nucleation the saddle point droplet
consists of randomly stacked planar structures with an in plane triangular
order. These results are consistent with previous theoretical results that
predict that the nucleation process in some metals is non-classical due to the
presence of long-range forces and a spinodal.
