The static recrystallization kinetics acquired from stress relaxation method
Original language description
Recovery can be described using the Avrami equation, which yields the proportion of recrystallized structure as a function of various deformation-related variables. Modern technique uses the stress relaxation phenomenon. By analysing the stress vs. timeplot, one can obtain information on the specimen's flow stress during the hold after deformation. A Gleeble simulator was used for an experiment with four temperatures (800 °C to 1 100 °C) and five strain rates (from 10-2 to 50 s-1) and the resulting strain magnitude of 0.2 or 0.4. Points denoting the start and end of recovery were identified on the curve. Constants of the Avrami equation were determined using these points. The advantages of stress relaxation tests include their simplicity, the opportunity to obtain a full-range curve for the volume fraction of recrystallized structure in a single test run and the effectiveness of mapping the softening phenomena.
