Pre-Lab Assignment for Composition & Cooling Curve
1. Determine the melting temperature for the following metals and metal alloys:
a. 100% Pb-0% Sn
b. 0% Pb-100% Sn
c. 38.1% Pb-61.9% Sn
d. 61.9% Pb-38.1% Sn
e. 50% Pb-50% Sn
2. Describe or show how data from cooling curves can be used to construct a phase diagram.
3. Draw the cooling curves for 100% Pb, 100% Sn, and 38.1% Pb-61.9% Sn. Specify the phase transition temperature(s) on the cooling curve as well as the phase of the material.
