(a)
Interpretation:
To determine eutectoid temperature, the composition of phase, amount of each phase of ZrO2-CaO.
Concept Introduction:
The graphical representation of the physical state of a substance which is under various conditions of pressure and temperature is known as phase diagram. A phase diagram has temperature on the x-axis and pressure on the y-axis. It is a type of chart which is used to demonstrate conditions at which
Answer to Problem 12.74P
The percentage of monoclinic and cubic is
Explanation of Solution
Sketch a horizontal line at
Therefore, from the graph mentioned above, the percentage of Monoclinic,
(b)
Interpretation:
To determine the eutectoid temperature, composition and amount of phase in Cu-Al at
Concept Introduction:
The graphical representation of the physical state of a substance which is under various conditions of pressure and temperature is known as phase diagram. A phase diagram has temperature on the x-axis and pressure on the y-axis. It is a type of chart which is used to demonstrate conditions at which thermodynamically different phases takes place and coexist at equilibrium.
Answer to Problem 12.74P
The percentage of composition obtained are
Explanation of Solution
Draw a horizontal line that passes through
At this particular temperature, β phase transforms to a phase, as shown in the diagram above.
Therefore,
(c)
Interpretation:
To determine the eutectoid temperature, composition and amount of each phase in
