Static recovery of A5083 aluminum alloy after a small deformation through various measuring approaches
文献摘要：
Static recovery was confirmed to be the dominant softening mechanism during annealing for the stud-ied A5083 aluminum alloy.The kinetics of static recovery,described based on the activation parameters(activation energy and volume of static recovery)and the static softening fraction,were mainly studied through two thermomechanical tests,namely,double-pass compression and stress relaxation tests.A new approach was proposed to measure the static softening fraction in the stress relaxation test.In general,a higher temperature or strain rate accelerates static recovery,while interestingly,the effect of pre-strain on static recovery is opposite in cases with and without external stress,owing to the enhanced static recovery by external stress during annealing.In addition,microhardness tests and electron backscatter diffraction(EBSD)characterization were also conducted to verify the accuracy of the results.The grain average misorientation approach based on EBSD characterization was confirmed to be effective in distin-guishing and quantifying static recovery.It is noteworthy that the special stress hardening phenomenon occurring at 400℃and 0.1/s is caused by strain aging,showing the complexity of the material behaviors after deformation of the studied aluminum alloy.
