摘 要：<正> For the grain refinement of super pure aluminium and commercial pure aluminium,Al-Ti-C master al-loy is better than Al-Ti alloy.It was shown by scanning electron microscope（SEM）and electron-probe mi-croanalyser（EPMA）that when the amount of titanium added is less than 0.15%,grain refinement of superpure aluminium is due to TiC particles rather than peritectic reaction.In addition,the presence of impurityelements in commercial pure aluminium plays an important role in grain refinement.The process of grain re-finement of aluminium by TiC is discussed in light of the TiC thesis.
