2. Using diagrams, briefly explain the following; i. Solvus ii. Eutectic iii. Eutectoid iv. Peritectic

Solvus: A solvus is a line or surface on a phase diagram which separates a homogeneous solid solution from a field of several phases which may form by exsolution or incongruent melting.

Eutectic: Relating to or denoting a mixture of substances that melts and freezes at a single temperature that is lower than the melting points of the separate constituents or of any other mixture of them.

Eutectoid: relating to or denoting an alloy which has a minimum transformation temperature between a solid solution and a simple mixture of metals.

Peritectic: A peritectic reaction is a reaction where a solid phase and liquid phase will together form a second solid phase at a particular temperature and composition.
