To date, complexions have been studied and utilized predominantly in either coarse-grained polycrystalline ... nanomaterials with tunable grain boundary structure. We begin by developing a ...

The grain size of the Al–Mg–Si alloy was reduced from 82 to 46 μm by the addition of GR alloy. The morphology of α-Al dendrites changes from coarse dendritic structure to fine equiaxed grains due to ...
