摘要

以5B02薄壁管材为研究对象, 进行330 ℃、380 ℃、400 ℃各保温1小时、2小时的退火实验。通过对不同试样进行拉伸实验发现:经过380 ℃, 2小时退火的试样塑性变形能力优于其他5组退火试样以及原始管材。通过对不同样品进行表面形貌及织构观察, 发现不同退火制度对管材内部织构有明显影响, 并导致材料塑性变形过程中滑移系种类及数量有所变化, 使得管材拉伸性能出现变化。

Abstract

In this paper the thin-walled pipes of 5B02 aluminum alloy were annealed at 330 ℃、380 ℃、400 ℃ and tensile properties were tested.The results show that the plastic deformation capability of the sample which annealed at 380 ℃/2h is better than other five samples and original pipes.Comparing the appearance and the texture in these six samples, it was discovered that the different annealing treatments had different effects on the texture of pipes, and made the kinds and the numbers of slip systems change during the plastic deformation.Then the tension properties were changed.
