Abstract

The hot deformation behavior of 6082 aluminum alloy at 350

00℃and 0.01

.00s-1 was analyzed by using hot compression testing on a Gleeble-1500 simulator

and the constitutive equation of6082 aluminum alloy was presented by means of fitting experimental data.The precision forging process of the 6082 aluminum alloy heat sink was simulated using Deform-3Dsoftware and the forming laws.The feasibility of numerical simulation was verified by trial production

which provided some references for engineering application.
