摘要

为保证有限元模型的计算精度，建立了应变补偿Arrhenius模型、修正的Fields-Backofen(m-FB)模型和修正的Zerilli-Armstrong(m-ZA)模型来预测铸态低合金Al-0.5Cu、Al-1Si和Al-1Si-0.5Cu的高温流变应力．为了确定三种本构模型的材料常数，在Gleeble-3800热模拟机上对三种铝合金进行了等温压缩试验．本构模型的预测结果与试验结果作比较以评估本构模型预测的准确性，并为上述三种合金选择最合适的本构模型（参数）提供依据．研究表明，应变补偿Arrhenius模型和m-ZA模型可分别作为Al-0.5Cu和Al-1Si合金最合适的本构模型，这两种本构模型同样可应用于Al-1Si-0.5Cu合金．然而，m-FB模型只能在高温和中等应变条件下应用于Al-0.5Cu、Al-1Si和Al-1Si-0.5Cu合金．

Abstract

To guarantee the computational accuracy of the finite element model

the strain-compensated Arrhenius-type model

modified Fields-Backofen(m-FB) model and modified Zerilli-Armstrong(m-ZA) model were established to predict the hightemperature flow stress of as-cast low alloyed Al-0.5Cu

Al-1Si

and Al-1Si-0.5Cu. To determine the material constants of these three constitutive models

isothermal compression tests of the three aluminum alloys were carried out on a Gleeble-3800 thermal simulator. The prediction results of the constitutive model were compared with the experimental results to evaluate the prediction accuracy of the constitutive models

and to provide a basis for selecting the most suitable constitutive models(parameters) for the three alloys mentioned above. It is found that the strain-compensated Arrhenius model and m-ZA model can be regarded as the most suitable constitutive models for Al-0.5Cu and Al-1Si alloys

respectively

and these two constitutive models also can be applied to Al-1Si-0.5Cu alloy. However

the m-FB model can be applied to Al-0.5Cu

Al-1Si and Al-1Si-0.5Cu alloys only under high temperature and medium strain conditions.
