Question

Which of the following cannot be obtained using a phase diagram?

(a) Melting temperatures of various phases

(b) Temperature range for solidification

(c) Equilibrium solid solubility

(d) Purity of materials

The question was posed to me in an online quiz.

I want to ask this question from Phases and Phase Diagrams in section Constitution of Alloys and Phase Diagrams of Engineering Material & Metallurgy

Answer 1

Right option is (d) Purity of materials

Explanation: A phase diagram is a graphical representation of the phases present in the system of materials at various temperatures, pressures, and compositions. It can be used to determine the melting temperature of various phases, the range of solidification, and the equilibrium solid solubility of one element in another.
