摘要有限元模拟可用于预测淬火过程中的残余应力和变形。所需本构方程的一部分涵盖了材料在过冷状态下的应变硬化模型(各向同性、运动学或混合型)。因此，在淬火和变形膨胀仪上对EN AW-6082等过冷铝合金进行了拉伸和拉伸/压缩试验。样品在膨胀仪中以超临界冷却速度进行了固溶退火和淬火。淬火后立即进行单轴拉伸或在不同温度下的拉伸/压缩试验。这些实验可以研究温度对包辛格效应的影响。包辛格效应的大小随着温度的升高而减小。最后，将计算结果应用于有限元软件SYSWELD®的材料模型中。
Abstract Finite element method (FEM) modelling can be used to predict residual stresses and distortion during quenching. One part of the necessary constitutive equations covers the strain hardening model (isotropic, kinematic or mixed) for the material in an undercooled state. Therefore, tension and tension / compression tests of undercooled aluminium alloys like EN AW-6082 were performed in a quenching and deformation dilatometer. Samples have been solution annealed and quenched in the dilatometer at a supercritical cooling rate. Immediately after quenching, uniaxial tension or tension / compression tests at varying temperatures have been performed. These experiments allow a study on the influence of the temperature on the Bauschinger effect. The magnitude of the Bauschinger effect was found to decrease with increasing temperature. Finally, the results have been implemented in the material model of the FEM-Software SYSWELD®.
