Microstructural Evolution of an Ultrafine-grained Cryomilled Al 5083 Alloy During Thermomechanical Processing

The microstructural changes in cryomilled and consolidated Al 5083 following compression testing at several temperatures are described. Prior to testing, the material had an average grain size of approximately 138 nm and exhibited a duplex microstructure, containing coarse grains between 500 and 200...
