1. For points F, G, H, I and J, determine the following:
a) Temperature and phase of the material (liquid, solid or 2 phase solid and liquid)
b) % solid and liquid
2. At point C (100% Ni), the Curie temperature is 350°C. At point D (68.5% Ni), the Curie
temperature is 0°C. Derive the equation of Curie temperature as a function of % Ni.
3. Calculate the Curie temperature and the density of the Cu-Ni alloy at 80% and 90% Ni.
Use the density table from the previous lecture.
TEMPERATURE, *C.
