Abstract
A significant grain refinement of pure aluminum is achieved upon addition of TiCN nanoparticles (NPs). Unlike the conventional inoculation, NPs can induce the physical growth restriction through the formation of NP layer on the growing grain surface. An analytical model is developed to quantitatively account for the NP effects on grain growth. The NP-induced growth control can overcome the inherent limitations of inoculation and shed light on a potential method to achieve grain refinement.
