Pb Sn Phase Diagram. Because as far as I know composition of this liquid means that the composition of the components in this liquid. That's the mixture from the first cooling curve plotted above.
Lead-Tin Example (Nicholas Fowler) In the Pb-Sn phase diagram Pb is component A and Sn is component B. microstructural component. Using The Lead-Tin (Pb-Sn) Phase Diagram Below…a. An isothermal (constant temperature) line through the alloy's position on the phase diagram when it is in a two phase field, intersecting the two adjacent solubility curves, is called a tie line (yes, that's the horizontal yellow line on the diagram).
A eutectic reaction is one in which the liquid phase solidifies to produce two solid phases. eg in the Pb-Sn eutectic system, Liquid reacts to form α +, ie L α +.
Such a phase diagram can be drawn from a series of cooling curves of alloys of different compositions in a manner analogous to that used for the eutectic, or solid solution diagram.
First we will repeat some basics about labeling phases. We can find it by drawing a tie line. In the Pb-Sn phase diagram Pb is component A and Sn is component B. microstructural component.
