Eutectic thermal equilibrium diagrams.

As can be seen from the drawing below these diagrams are built up in the same way as the solid solution diagrams i.e. with the use of cooling curves but there are of course differences between these thermal diagrams and the solid solution thermal equilibrium diagrams, the reason for this is of course due to the fact that in eutectic alloys the metals are only totally soluble in each other in the liquid state.
