Al-Zn-Mg-(Sc) 합금의 고온가공성에 미치는 Sc 함량의 영향
Effect of Scancium Content on The Hot Extrusion of Al-Zn-Mg-(Sc) Alloy
초록
The effects of scandium content and extrusion parameters on Al-Zn-Mg-(Sc) alloys were examined. Three kinds of Al-Zn-Mg-(Sc) alloys with up to 0.30 wt.% Sc were prepared. The compression test was conducted to investigate the microstructure evolution during hot deformation. Despite of microstructural differences in the alloys, deformation behaviors were very similar. After extrusion at
