Bending properties

tensile properties and hardening precipitates of 6082-T6 aluminum plates were investigated under production conditions

and the relation equation between tensile property and bending property was attempted to be established and verified.The results show that the plate bending property can be evaluated quantitively by the elongation

and the equation among critical elongation（δ）

plate thickness（t）and bending radius（r）followsδ=（t/2）（t/2+r）.The higher elongation（

>

17%）can be obtained by adopting the 155℃×（4

1

6）h under-aging process with the combination of clusters and finest need-likeβ″precipitates

resulting in the good plate bending property while keeping tensile properties.In addition

the tensile property data in 6082 plate production of two aging processes（170℃×12 h、155 ℃×12 h）was compared

and it was verified that the higher elongation and tensile strength could be obtained by adopting the 155 ℃×12 haging treatment.
