as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes
