前言早期的研究发现,向铝和钼合金中加入少量钛有细化晶粒作用。因此,用AlTi中间合金处理铝熔体的传统铸造工艺方法已有80年以上的历史了。此法至今仍为某些冶金工作者在某些场合所使用。进一步的研究查明,钛与硼结合使用,在钛浓度低得多的情况下能大大增进成核过程。这一发现导致人们研制了AlTiB中间合金。最近的技术证明,采 Preface Earlier studies found that the addition of a small amount of titanium to aluminum and molybdenum alloys has the effect of refining grains. Therefore, the traditional casting process for treating aluminum melt with AlTi master alloy has been more than 80 years old. This method is still used by some metallurgists on some occasions today. Further studies have shown that the combination of titanium and boron can greatly enhance the nucleation at much lower titanium concentrations. This discovery led to the development of AlTiB master alloy. Recent technical proof, mining
