| Abstract: | To obtain specific properties and performance from a metallic material, it is necessary to control the microstructure. This imposes a need to monitor closely and/or predict microstructural transformations during downstream processing. One of the main features that determine the properties of wrought metals and alloys is the status of their matrix, which may be changed by thermomechanical treatment procedures. Different softening processes, such as recovery, recrystallization (RX) or grain growth, may occur in cold- and hot-worked materials. The present paper focuses on different aspects of RX and the microscopic methods used for its study. Examples of the usefulness of light microscopy examinations in the study of RX of several aluminum alloys are given. |
