冷角轧制工艺（CARP）已成为一种潜在的连续剧烈塑性变形技术，可以加工具有良好力学性能的大块金属板材。CARP技术包括用单个旋转辊对板材进行冷轧，然后通过弯曲通道对板材进行等通道角压。本工作采用有限元方法（FEM）对不同铜和不锈钢合金的加工条件进行建模，包括不同的摩擦值和加工速度。仿真结果揭示了这些工艺参数对金属板上一次CARP加工后的应变分布、应变速率、应力（金属板和CARP刀具中的应力）、温度和扭矩要求的影响。通过对铜片表面CARP后的硬度分布和微观结构的实验表征，验证了模型的正确性。利用有限元分析的结果估算了不同金属合金在不同加工条件下的能量。最后，本文讨论了扩大鲤鱼技术规模的可行性。图形抽象
Cold angular rolling process (CARP) has emerged as a potential continuous severe plastic deformation technique enabling the processing of bulk metal sheets with improved mechanical properties. The CARP technique involves a combination of cold rolling of a sheet by a single rotation roller followed by equal-channel angular pressing of the sheet passing through a bent channel. The present work uses finite element method (FEM) to model CARP by considering processing conditions, including different friction values and processing velocities for different copper and stainless steel alloys. The simulations reveal the influence of these processing parameters on distributions of strain, strain rate, stress (in both the metal sheet and the CARP tool), temperature, and torque requirements through one pass of CARP on the metal sheets. The modeling results are validated by the experimental characterization of the hardness distribution and microstructure after CARP on a copper sheet. The results from FEM are used to estimate the energy incorporated into different metal alloys at various processing conditions. Finally, this study discusses the feasibility of scaling up the CARP technique.Graphical abstract
