The activation enthalpy between
Answer to Problem 9.4P
The activation enthalpy between
Explanation of Solution
Given:
The logarithm of stress is
Concept used:
Write the expression for tensile stage II creep rate.
Here,
Calculation:
Refer to Figure 9.5 “The log of the stage II creep strain rate of zirconium as function of the log of stress, at three temperatures” to obtain the value of strain rate corresponding to logarithm of stress as
Substitute
Substitute
Divide equation (2) by equation (3).
Conclusion:
Thus, the activation enthalpy between
