| 제목 | Exploring the deformation behavior and microstructure of Al based materials |
| 초록 | Exploring the deformation behaviors and microstructures on micrometer and nanometer scales are very important for understanding Al based material property and its application to engineering. In this talk, I introduce the deformation behaviors of Al6061/nano-Al2O3 composites and Al-Mg alloys, which was tested by using both compression and torsion tests. The composite fabricated by the infiltration method consisted of an Al matrix and Al2O3 particles with a mean size of 200 nm. The hot deformation mechanism in Al6061/nano-Al2O3 composites is believed to occur through dynamic recrystallization, where fine equiaxed grains and dislocations were observed at the deformed specimens [1]. Strain distribution in plane-strained (rolling) and simple-sheared (torsion) Al–Mg alloy has been estimated using both X-ray line profile analysis and electron backscatter technique. The strain analyses under unified texture distribution by orientation rotation showed that torsion has relatively homogeneous strain distribution regardless of texture component in contrast to inhomogeneous strain in rolling. In addition, annealing texture of torsion has more random texture than inhomogeneous rolling texture. [2, 3] REFERENCES 1. K. H. Yeon, H. S. Park, M. S. Kim, S. B. Yu, J. K.
