Abstract Scope |
Accumulative roll bonding (ARB) is a severe plastic deformation technique used to produce ultrafine grained material. Materials processed by ARB are attractive as they exhibit enhanced strength at ambient temperatures due to Hall-Petch strengthening. Some alloys also demonstrate low temperature superplasticity, which has the potential to decrease cycle time and cost in superplastic forming operations. Lower temperature superplasticity behavior can be quite sensitive to microstructure and processing conditions, and microstructural development during forming operations can have significant effect on formability and post-forming properties. ARB is necessarily a directional processing pathway, so considerations of texture development and strain path are also important. |
