1 - Question

The ratio of ______ is frequently used in the interpretation of recrystallization data.
a) yield strength of test specimen and standard specimen
b) temperature and time
c) rate of nucleation and rate of growth
d) rate of recrystallization and polygonization
View Answer Answer: c
Explanation: The ratio of the rate of nucleation to the rate of growth, N to G, is frequently used in the interpretation of recrystallization data. If it is assumed that both N and G are constant or are average values for an isothermal recrystallization process, then the recrystallized grain size can be deduced from this ratio.
