Paper Summary:

The experiment discussed in this paper aims to generate experimentally the lead-tin phase diagram from various proportions of the two metals in this binary system. It involves the preparation and heating in a test tube of mixtures containing 90%Pb-10%Sn, 80%Pb-20%Sn, 60%Pb-40%Sn, 40%Pb-60%Sn, and 20%Pb-80%Sn. The paper explains that the experiment requires the use of a thermocouple to monitor the temperature reading every 5 seconds until it drops off to 160 degrees C. Five cooling curves (temperature versus time), 1 for each mixture are generated, taking notes on the points of arrest and the critical temperatures. The paper shows that the integration of all the cooling curves produces the lead-tin phase diagram. The paper includes diagrams.

From the Paper:

"The simplest phase diagrams are those of the binary alloys, a binary alloy being one that contains two components. In this type of phase diagram, temperature and composition are the variable parameters, the temperature usually being relegated to the y-axis and the composition to the x-axis (where the two composition scales of the two components run opposite to each other in magnitude, the 100% composition of each component coinciding with the 0% composition of the other component, and vice versa)."
