| 제목 | Fabrication and Evaluation of complex aluminum alloy sheets with heterogeneous microstructure by cold roll bonding process |
| 초록 | Recently, lots of studies on lightweight of automobile have been done because of importance of the energy saving and green environment. Especially, the aluminum alloys for automotive body panel have been studied extensively because of their benefits such as medium strength, good formability and lightweight. It is also expected that the substitution of such aluminum alloys for steels will result in great improvements in energy economy, recyclability and life-cycle cost. Therefore, the studies on development of newly designed Al alloys to satisfy both strength and plastic workability are needed for their wide applications to automotive industry. In the way, cold roll bonding (CRB) which has been widely used in manufacturing large sheets can be one way to design various layered materials to have the promising mechanical properties. Compared to other processes, the CRB is very effective because it is easy to be automated and simple to set up continuous process system. Further, the CRB has a great merit to fabricate various clad materials through various combination of metallic sheets. Therefore, many researches have been carried out on the fabrication and evaluation of layered materials processed by the CRB. The author has studied on fabrication of multi-layer complex aluminum alloy sheets through the CRB including accumulative roll bonding(ARB) process. In this study, the examples for various Al clad materials having heterogeneous microstructure are introduced. |
