Grain refinement of hypoeutectic Al-7wt.%Si alloy induced by an Al–V–B master alloy

The current study investigates the grain refinement of an Al-7wt%Si alloy with addition of Al–V–B master alloy. It is found that the Al–V–B master alloys can overcome the Si poison effect on grain refinement and refine the as cast grain structure of the Al-7wt%Si alloy effectively. A remarkable grai...
