海德尔科公司（Ｈｙｄｅｌｃｏ）新近研制成一种高效的铝及铝合金晶粒细化剂合金，其商品名称为Ｈｙｄｌｏｙ合金。这种 Ａ１—Ｔｉ—Ｂ晶粒细化剂的特点为：不含以铝化钛形式存在的过量钛；细化效果与稳定性大为提高；由于添加量减少生产成本有所下降；聚集的 ＴｉＢ２化合物
Hydelco (Hydelco) recently developed a highly efficient aluminum and aluminum alloy grain refiner alloy, the trade name Hydloy alloy. The A1-Ti-B grain refiner is characterized by the absence of excess titanium present in the form of titanium aluminide; a significant increase in refinement and stability; a reduction in production costs due to reduced addition; TiB2 compound
