This set of Engineering Materials Science "Multiple Select Questions & Answers" are based on "PHASE DIAGRAM"
PHASE DIAGRAM
Multiple Select Questions (MSQ)
Hello reader, here you can find some MSQ with answers. But before reading this I will suggest you take a practice test on these questions given below. so you can understand your strength on this topic.
Click here to go Practice Test section on this topic namely Phase Diagram.
But if you want to read this topic first and then practice it then read it carefully. The Multiple Select Questions (MSQ) based on the Phase Diagram are given below:
1) Which of the following is correct with respect to phase?
Correct Answer is "A", "C"
The phase is a physically distinct, chemically homogeneous, and mechanically separable part of a system.
2) Which of the following is/are true about a phase diagram?
Correct Answer is "A:, "B", "C"
Phase diagram indicates the temperature at which different phases start to melt, the Relative amount of different phases, and Solid solubility limits.
3) Liquid phase is involved in which of the following reaction:
Correct Answer is "A", "B"
The liquid phase is involved in a eutectic and peritectic reaction. In eutectoid reaction, one solid phase on cooling gives 2 solid phases and peritectoid is reverse of eutectoid where no liquid phases involved.
4) Example of an isomorphous system is/are
Correct Answer is "B", "D"
Examples of isomorphous systems are Cu – Ni and Ag – Au. Cu – Ag and Pb – Sn are the eutectic system.
5) Which of the following can be obtained using a phase diagram?
Correct Answer is "B", "C", "D"
From the phase diagram, one can obtain the Temperature range for solidification, Equilibrium solid solubility, and Melting temperatures of various phases.
6) Which of the following invariant reaction occurs in the Fe – C diagram?
Correct Answer is "A", "B", "C", "D"
In Fe – C diagram Eutectic (1147°C), Peritectic (1493°C), Monotectic (1493°C), and Eutectoid (727°C) all 4 invariant reactions occurs
7) Which of the following microstructural characteristics are important for a multiphase alloy?
Correct Answer is "A", "B", "C"
(i)The number of phase present, (ii) The relative proportions of the phases, and (iii)The manner in which the phases are arranged all these three microstructural characteristics are important for multiphase alloy
8) From the phase diagram one should know
Correct Answer is "A", "B", "C"
From the phase diagram, one should know (i) The phase present (ii) The phase compositions, and (iii) The phase amounts
9) Which of the following factors affect the microstructure of an alloy?
Correct Answer is "A", "B", "C"
What alloying elements are present, the concentration of the alloying elements, the heat treatment of the alloy all these three factors affect the microstructure of an alloy
10) For binary phase diagrams main variables are
Correct Answer is "A", "C"
For binary phase diagrams, the main variables are Temperature and Compositions
