First, melting occurred in the region with low melting point phase and high energy, eg. at the root of dendrite arm. Due to the effect of surface tension and interface curvature, grain will take place slow coarsening when the atom disperse from the high curvature region to the low curvature region.

Melting first occurred in the low melting point phase and the  high-energy region, for example, the roots of dendrite arms. As the effects of surface tension and interface curvature,  atomic diffusion from the high curvature regions to low-curvature regions occured slowly so that made grain slow coarsening.
