, and the stretching tests were carried out to investigate the influences of polymer core thickness on the limit dome height of the sandwich sheet. The forming limit curves for three kinds of sandwich sheets were obtained. The experimental results show that the forming limit of the AA5052/polyethylene/AA5052 sandwich sheet is higher than that of the monolithic AA5052 sheet, and it increases......
powder cold roll forming and reactive synthesis JIANG Yao, HE Yue-hui, TANG Yi-wu, LI Zhi, HUANG Bai-yun (State Key Laboratory of Powder Metallurgy, Central South University, Changsha 410083, China) Abstract: Ti-Al alloy sheets were fabricated successfully by element powder cold roll forming and reactive synthesis. The size and relative density of sheet bars were 500mm×230mm×1.5mm, 85.9......
