The production of stamped parts from rolled aluminum sheets requires different tempers and different thermal routes. While the slip and hardening behavior of the alloy strongly depends on the temper and the process temperature, the crystallographic texture remains largely static. Although the plastic anisotropy of rolled sheet is largely a function of the crystallographic texture, a dependency of plastic anisotropy on the temper has been reported for 6xxx series alloys, indicating that slip and hardening behavior have some influence. A systematic investigation of the effect of the slip and hardening behavior on the plastic anisotropy, however, does not exist. In this study, a crystal plasticity fast Fourier transform framework is utilized to predict the r -values, a common measure for plastic anisotropy, of two widely used commercial aluminum alloys possessing different crystallographic textures, AA6016 and AA5182. To investigate the sensitivity of the r -values to c...

晶体塑性建模参数对轧制铝板塑性各向异性影响的数值研究

用轧制铝板生产冲压件需要不同的回火和不同的热路线。尽管合金的滑移和硬化行为在很大程度上取决于回火和加工温度，但晶体织构在很大程度上保持静态。尽管压延板的塑性各向异性很大程度上取决于晶体织构，但据报道，对于6xxx系列合金，塑性各向异性与回火有关，这表明滑移和硬化行为有一定影响。但是，还没有对滑动和硬化行为对塑性各向异性的影响进行系统研究。在这项研究中，利用晶体可塑性快速傅里叶变换框架来预测r值，r值是塑性各向异性的常用度量，具有广泛的晶体学织构的两种广泛使用的商用铝合金中的一种是AA6016和AA5182。研究r值对c的敏感性
