7. Solidification and segregation coefficient
During cooling, liquid solidification begins at the temperature of intersection of the vertical line drawn on the alloy composition x 0 diagram with the liquidus line (figure 18 ). When only a single solid phase is formed, the composition of the first crystals can be read on the diagram at the intersection of the horizontal isotherm at the start of solidification with the solidus line. As solidification continues, the temperature falls, the composition of the liquid follows the liquidus and that of the solid the solidus. In the case of figure 18 both phases in equilibrium become simultaneously enriched in element B, but through...

Diagram classification
In this folder, the diagrams are arranged in alphabetical order of the symbol of the element concerned, which comes first in alphabetical order among the elements making up the alloy; then, for a given element, in alphabetical order of the symbol of the second element.
Example
we find Fe-C to C-Fe.

As-Cu (arsenic-copper – figure )
This diagram has recently been completely revised. The relationships between phases and their compositions are now well known; there are apparently no other intermediate phases richer in arsenic than those shown in the diagram.
