Paper Title: Deformation behavior of AA6061 with 5% by volume Al2O3 under hot deformation condition
Unique Id: IJSDR2305231
Published In: Volume 8 Issue 5, May-2023
Abstract: The hot deformation behavior and constitutive relationship of AA 6061 aluminum alloy with 5% by volume Al2O3 was studied after carrying out hot isothermal compression tests using Gleeble 3800 thermo-mechanical simulator, range of temperature and strain rate was 573˚K to 773˚K and 0.001 to 1 s-1, respectively and the height reduction was of 70%. One of the important features observed in the material is Dynamic Strain Aging, which was observed from temperature ranging from 573˚K to 673˚K at strain rate of .001, .01, .1, 1 s-1. The modified Arrhenius type constitutive equation models based on Zener-Holloman parameter were used. The power law and sine-hyperbolic law were used to calculate activation energy. The value of activation energy using sine-hyperbolic law comes out to be 212.205 kj/mol. The value of activation energy was found to be much higher than self diffusion activation energy of pure aluminum alloy (144 kj/mol). The high value of activation energy suggests that DRV or DRX can be a leading softening mechanism.
