A novel fading-resistant A1-3B grain refiner for Al-Si alloys

摘要：

A novel, fading-resistant AI-3B refiner containing AIB12 particles was produced via the halide salt route by reacting compacted KBF4 block with molten aluminum at 950°C. The result of grain refinement test on AI-7Si alloy shows that rejuvenation of refining efficiency occurs between 30 to 60 minutes with 1.0wt.％ addition level. The presence of AIB12 in the refiner is responsible for the capability of fading-resistance.
