Study on Flow Stress Model of AA5005 Material

Abstract:

Due to the continuous emergence of new alloys and the improvement of basic research requirements for aluminum alloy, researchers need to further study the flow constitutive relationship of new aluminum alloys. This paper used Model MTS-810 tensile machine to conduct tensile tests on AA5005 aluminum alloy at temperature of 360°C and strain rate of . Hollomon model, Swift model, Voce model, Voce+Voce model were used to compare the fitting accuracy with the experimental stress-strain curves, and the fitting parameters required by each formula were obtained from the fitting results, so as to obtain the constitutive model of AA5005 aluminum alloy. The Voce+Voce model which with more fitting freedom degree, lower flow stress increasing rate and saturation rate is most suitable to describe flow stress relation of aluminum alloy AA5005.
