用晶体塑性有限元方法模拟了多晶间隙无间隙钢的平面应变压缩过程。为了捕捉相邻颗粒之间的相互作用，模拟中使用了简化的准三维几何网格。分析表明，取向梯度不仅取决于颗粒的初始取向，而且还取决于相邻的颗粒。模拟结果表明，根据主要织构成分的不同，变形晶内的取向分布可分为三种类型。模拟结果为定量评价冷轧IF钢的取向相关储能提供了一种方法。在特定晶界的储存能量的积累也是初始取向和邻近颗粒的函数。
The plane strain compression of polycrystalline interstitial free steels is simulated using the crystal plasticity finite element method. In order to capture the interaction between neighboring grains, a simplified quasi 3-D geometric mesh is used in the simulation. The analysis shows that the orientation gradients depend not only on the initial orientation of the grain, but also on the neighboring grains. The simulation shows that the distribution of orientation in the deformed grains can be classified into three types based on the main texture components. The simulations provide a method to quantitatively evaluate the orientation-dependent stored energy in cold-rolled IF steels. The accumulation of stored energy at the specific grain boundaries is also a function of initial orientations as well as neighboring grains.
