Jan 17, 2020 · In our previous studies , to increase the wettability of nanoparticles with the melt of A356 alloy, solid-state modification of ceramic nanoparticles in a ball-mill was conducted, and composite powders with superstructures were injected into the semisolid melt. It was found that stirring in the viscous melt was essential but not enough, and it seems that liquid-state stirring is also required for …
