The phase diagram is a graph showing the relationship between the phase that occurs at temperatures pressure and different chemical ingredients
information from the phase diagram: melting point. Start point, end point, melting ice;
Birth phaseLiquidus line means it is drag the beginning of the melting of alloy liquid phase breaks with another phase of
Solidus line means a drag-end solution of various alloy solid-phase breaks with the phase.
The principle of equilibrium of the masses will be able to calculate the birth phase of point, so right.
