摘要：

The history of grain refinement with AlB2 in Al-Si and Al-Si-Cu casting alloys is reconsidered in light of findings published recently by Zheng and co-workers. When using boron as a grain refiner, some problems may be encountered. These are considered briefly. Fundamental aspects of grain refinement are also discussed and useful future experiments proposed.
