摘要:

建立多尺度模型阐明了镁合金薄板再结晶和织构演变机制。先用有限元法数值计算异步温轧工艺过程，得到了等效塑性应变、应变速率等结果，并以此作为初始边界条件引入基于位错密度演化的硬化方程，得到了VPSC(Visco-Plastic Self-Consistent)粘塑性自洽模型、实现了CA(Cellular Automata)元胞自动机模型的耦合计算，得到了宏观尺度上的应力与应变、微观尺度上的动态再结晶微观组织和变形织构。研究了异步温轧过程中应变速率对动态再结晶微观组织的影响，并用电子背散射衍射技术(EBSD)实验验证了在不同冷却条件下温轧AZ31镁合金薄板的微观组织。模拟结果表明：适当提高应变速率可细化晶粒；轧制后空冷处理的板材基面织构的弱化程度更高，有利于提高沿板材厚度方向的变形能力。

Abstract：

The mechanism of recrystallization and texture evolution of Mg-alloy sheet was elucidated by means of an established multi-scale calculation model. First of all, the numerical calculation of asymmetric warm-rolling process was carried out by using finite element method, and the equivalent plastic strain and strain rate were obtained as the reference boundary parameters conditions. By introducing the hardening equation based on dislocation density evolution, the coupling calculation of the viscoplastic self-consistent (VPSC) model and cellular automata (CA) model were achieved. The stress and strain, as well as the dynamic recrystallization microstructure and deformation texture on the microscopic scale were obtained. Based on this method, the influence of strain rate on dynamic recrystallization microstructure variation during asymmetric warm-rolling was calculated. The microstructure of warm-rolled AZ31 Mg-alloy sheet prepared by different cooling conditions was experimentally verified by electron back-scattered diffraction (EBSD). The simulation results show that the grain can be refined by increasing the strain rate appropriately and the experimental results show that the weakening degree of the basal texture of the alloy sheet by air cooling after rolling is higher, which is beneficial to the enhancement of the deformation ability of the Mg-alloy sheet along its thickness.

Key words： metallic materials multi-scale model asymmetric warm-rolling dislocation density Visco-Plastic Self-Consistent model dynamic recrystallization
