(a) The phase diagram of the binary system, neodymium-scandium (Nd-Sc) is given below. There are two polymorphs in the solid state: α which is hexagonal close packed (HCP) and β which is body-centered cubic (BCC).
Identify all phases present at points 1, 2, and 3.

(b) Are there any examples of a three-phase equilibrium in this phase diagram?
Yes, there is a eutectic at 700 degrees C and 60 at. % Sc.
Yes, there is a eutectoid at 800 degrees C and 22 at. % Sc.
Yes, there is a peritectic at 800 degrees C and 22 at. % Sc.
No, there are no three-phase equilibrium points in this diagram.
