Abstract

Different temperature and time parameters were adopted in the stress relieving annealing processes of 5B70 and 5A06 aluminum alloys. Then, the mechanical properties and the variation regularity of residual stress of 5B70 and 5A06 aluminum alloys before and after stress relieving annealing were studied. The results show that after stress relieving annealing, tensile strength and yield strength of 5B70 aluminum alloy decrease. Meanwhile, elongation and contraction ratio of section improve. The removing effect of residual stress is remarkable. Under the same stress relieving annealing process, the performance degradation of 5B70 aluminum alloy is smaller than that of 5A06 aluminum alloy. Finally, the stress relieving annealing schedule of 5B70 aluminum alloy was obtained to be 180±10 C and l hour. And the residual stress caused by forming is reduced by 50%.
