Abstract

The settling behaviour of heterogeneous nucleating particles such as TiAl3, TiB2, AlB2 and TiC in liquid Al has been studied through vertical sectioning experiments. The experimental results obtained were correlated with the settling rate of the particles calculated using the Stokes' law. The TiB2 and TiC particles show larger settling tendency among all particles studied. The overall settling behaviour of the particles is largely influenced by their size distribution in their respective master alloys, their agglomeration and dissolution behaviour in the liquid Al.
