日本大阪府立大学发明了一种延伸率达世界最高水平——56倍以上的铝青铜系超塑性合金。在800℃时对其合金施加0.27公斤/毫米~2的力,便会延伸。即使采用比现有的超塑性材料快2个数量级的1～100毫米/分速度进行拉伸,合金并不断裂,其强度亦不下 Osaka Prefecture University invented an elongation of more than 56 times the world’s highest level of aluminum bronze superplastic alloys. At 800 ℃ when its alloy is applied 0.27 kg / mm ~ 2 force, it will extend. Even with two orders of magnitude faster than existing superplasticic materials at 1-100 mm / min, the alloy does not break and its strength does not
