7.33 Briefly cite the differences between recovery and recrystallization processes.
7.34 Estimate the fraction of recrystallization from the photomicrograph in Figure 7.21c.
(a) What was the original grain diameter?
(b) What grain diameter would you predict after 200 min at 650°C?
7.39 An undeformed specimen of some alloy has an average grain diameter of 0.050 mm. You are asked to reduce its average grain diame- ter to 0.020 mm. Is this possible? If so, explain the procedures you would use and name the processes involved. If it is not possible, explain why.
7.40 Grain growth is strongly dependent on temperature (i.e., rate of grain growth in- creases with increasing temperature), yet tem- perature is not explicitly given as a part of Equation 7.9.
(a) Into which of the parameters in this expression would you expect temperature to be included?
(b) On the basis of your intuition, cite an explicit expression for this temperature dependence.
