Abstract

This chapter is devoted to the topics of deformation microstructure and recovery. The conventional notations and understandings of recovery at low strains are briefly reviewed, followed by a presentation of materials and processing parameters controlling recovery and the microstructure-property relationship during recovery. New discoveries on deformation microstructures from the last 30 years are briefly reviewed with focus on face-centered cubic (FCC) metals with high stacking fault energy. The strong effect of microstructure on recovery is exemplified by a presentation of novel dynamic and static recovery mechanisms in ultrafine microstructures.
Deformation microstructure not only determines the properties of a deformed metal but also provides the driving force for recovery and recrystallization; recovery competes with recrystallization in restoring microstructure and properties and at the same time facilitates nucleation of recrystallization. Therefore, such topics are important in the design, processing and understanding of novel metals with optimized properties.
