4. Summary

In summary, the methods to measure the vacancy migration energy by using HVEM were described and discussed in this chapter. Considering other sinks effects, a new nonlinear method was developed to measure vacancy migration energy according to the relationship of the reciprocal of irradiation temperature and growth speed of dislocation loops. Meanwhile, an influential factor relating to the effects of other sinks was also presented. The characteristics of three methods for measuring vacancy migration energy were also discussed in detail, which can help to select the appropriate method to measure the vacancy migration energy in different situations.
