Grain Refinement in Near-Eutectic Al-Si Alloy with Master Alloys Fabricated by Slip Casting Using Nano-Nb2O5 as a Precursor

Aluminum-silicon (Al-Si) alloys are staple materials in the automotive and aerospace industries. However, effective grain refinement of alloys containing > 4 wt.% Si remains challenging with traditional Al-Ti-B master alloys. This difficulty arises from the silicon poisoning effect, in which Si reacts with titanium to...
