本人有一铝箔（40微米），想对其延展性进行表征？
不知道有没有什么方法适用？
能用断裂伸长率说明么？呵呵
如有国标或国际标标准指导最佳。
(*^__^*)
延展性可以用塑性来反映。
塑料测试一般做什么测试？
断裂伸长率？断面收缩率？请砖家解答呵呵

没有搞金属检测的高

延展性和塑性是不是一样啊？

延展性是不能具体表征的，通常通过塑性指标能够定性说明延展性大小。

It is extremely difficult to use the
results from these tests analytically to accurately describe
plastic deformation in other applications. This
drawback is being addressed by instrumented indentation
test standards (ISO 14577 (Metallic materials –
Instrumented indentation test for hardness and materials
parameters) and efforts underway at ASTM). The
commercial importance of hardness testing cannot be
underestimated and justifies an entire Sect. 7.3 devoted
entirely to hardness.

by any means. It is extremely difficult to use the

可以用微拉力测！

延伸率和断面收缩率都可以的。
