- Abstract
- A large shear flow under high-ratio differential speed rolling promoted the formation of a novel microstructure in which carbon nanotubes were uniformly dispersed and directionally aligned in the aluminum matrix. As a result, the processed composite exhibited a high yield stress (similar to 400 MPa) and good ductility (similar to 10%). (c) 2013 Elsevier B.V. All rights reserved.
