The short-range order in undercooled melts is of fundamental interest, beca
use it is predicted to influence the energy of the interface between the li
quid and a solid nucleus. This in turn has a decisive impact on the nucleat
ion behaviour of solid phases from the undercooled melt, and by means of th
at determines the properties of the as-solidified materials.
This work gives a review of theoretical and experimental investigations on
the short-range order in undercooled melts and its effect on the solid-liqu
id interfacial energy.
