| 摘 要： | 分析了金属轧制变形的模拟过程,提出了新的形变模型(PC模型)。PC模型修正了多晶体内各晶粒变形时的切变边界条件,允许各种切变在变形过程中部分存在,从而使模拟更接近实际晶体变形过程。与多晶铝轧制织构的比较表明,PC模型能更好地表达轧制过程中面心立方金属各晶粒取向,在取向空间内的流动倾向及最终稳定位置。

| Abstract: | The simulation process of rolling deformation in matels is analysed, and a new deformation model (PC-model) is suggested. The new model modifies the shear condition of deformation grains in polycrystal, in which the shears are partially free, so that the simulation could further approach the real cases. According to comparison with rolling texture in Al polycrystal the PC-model could show more accurately the flow tendency of grain orientations in f.c.c matels and their final stable positions in orientation space. |
