Texture and Microstructure in AA 3103 Sheets Deformed by Continuous Confined Strip Shearing Process
CCSS 가공에 의한 AA3103 판재의 집합조직 변화와 결정립 미세화에 관한 연구
Abstract
Strip samples of AA 3103 were deformed by Continuous confined strip shearing (CCSS). The CCSS process was designed to provide a repeated shear deformation in metallic sheet materials. CCSS led to the formation of characteristic shear textures comprising a pronounced｛111｝＜uvw＞ orientations. The intensity of the deformation texture hardly increased with increasing number of CCSS passes. EBSD equipped in a FESEM with a high beam current revealed the formation of fine grains even after annealing for the recrystallization.
