摘要
采用Gleeble 3500热模拟试验机模拟了在不同温度和应变速率下6082铝合金的流变力学行为,建立了6082铝合金的本构方程,得到了应力-应变曲线。结果表明,6082铝合金流变应力随变形温度的升高而降低,随应变速率的增加而增大。本构方程对峰值应力的计算结果与试验数据具有较高的一致性。
The Gleeble-3500 thermal simulator was used to simulate the rheological mechanical behavior at different temperatures and strain rates in order to build the constitutive equation of 6082 aluminum alloy. The stress-strain curves were gained. The results show that the flow stress of 6082 aluminum alloy decreases with the increase of deformation temperature and increases with the increase of strain rate. The data calculated with constitutive equation are consistent with experiment data.
