Recrystallization of hot-worked austenite during continuous cooling
- 24 Downloads
During continuous cooling of hot-worked austenite primary and secondary recrystallization occur, which can be determined from changes in the austenite grain size.
The rate at which different stages of the recrystallization process occur depends on the deformation, alloying, and deformation temperature.
The grain size is most regular through the section of cylinders subjected to deformation and cooling conditions that result in the greatest grain refining.
The variation in the size and uniformity of austenite grains in the recrystallization process affects the mechanical properties of the steels investigated. The optimal combination of mechanical properties results from complete primary recrystallization with no secondary recrystallization.
