394 • Chapter 10 / Phase Diagramsferrite phase in addition to pearlite. On the other hand, pearlite and proeutectoid
cementite constitute the microconstituents for hypereutectoid alloys—those with
carbon contents in excess of the eutectoid composition.IMPORTANT TERMS AND CONCEPTS

QUESTIONS AND PROBLEMS
Additional problems and questions for this chapter may be found on both Student and
Instructor Companion Sites atwww.wiley.com/college/callister.Solubility Limit10.1Consider the sugar–water phase diagram of
Figure 10.1.
(a)How much sugar will dissolve in 1000 g
of water at 80◦C (176◦F)?(b)If the saturated liquid solution in part
(a) is cooled to 20◦C (68◦F), some of the
sugar will precipitate out as a solid. What
will be the composition of the saturated
liquid solution (in wt% sugar) at 20◦C?
(c)How much of the solid sugar will come
out of solution upon cooling to 20◦C?
