Segregation during freezing

Segregation during freezing for an alloy containing 5% B and having a distribution coefficient of k = 0.2. [Pg.92]

As we have noted in Chapter 6, some salts have a solubility that decreases with decreasing temperature. In this case these salts will crystallize during the freezing process, which can lead to chemical segregation into different salt crystals within the droplet. When the solubility increases with decreasing temperature, a more homogeneous mixing of the various metal salts is found. [Pg.339]

The dashed lines show the final concentration distribution for the cases of complete and no mixings in the melt, respectively.
