摘要/Abstract

摘要： 金属复合板在现代工业诸多领域都有着广泛的应用，其中冷轧是制备金属复合板的主要手段，为了制备性能更优异的复合板，有必要对其复合机理和复合过程行深入研究。薄膜理论为目前最广为认可的冷轧复合机理，认为冷轧过程中金属表面脆性硬化层在大塑性变形下开裂，暴露出来的新鲜金属在较大轧制压力作用下挤入裂缝形成机械咬合是引起复合的主要原因，在此理论基础上，许多研究指出异种金属间形成复合所需的压下率取决于较软金属，然而实际生产中金属间性能差异越大，复合产生所需的压下率就越大，目前对此仍未有合理的解释。为了能够揭示异种金属冷轧过程中的复合机理，通过对MARC软件进行二次开发，建立一个能完整并准确描述冷轧复合过程中界面间复合与分离的有限元模型，在此模型基础上，揭示了界面间剪应力在冷轧复合过程中的重要作用，完善了冷轧复合机理，并通过该机理解释了材料性能及压下率等因素对复合过程产生影响的原因。

Abstract: Metal composite plates have extensive applications in many fields of modern industry, among which cold rolling is the main method for preparing metal composite plates. In order to prepare composite plates with better performance, it is necessary to study the composite mechanism and process in depth. As the most widely recognized cold rolling composite mechanism currently, the film theory believed that the brittle hardening layer on the metal surface cracks under large plastic deformation, and squeezed into the crack under large rolling pressure to form mechanical bite during cold rolling, which is the main reason of composite. Based on this theory, many studies have pointed out that the reduction rate required for forming composite between heterogeneous metals depends on the softer metal, however, the greater the performance different between metals, the greater the performance difference between metals in actual production, there is still no reasonable explanation for this. In order to reveal the composite mechanism of heterogeneous metals in the cold rolling process, a finite element model which can completely and accurately describe the interfacial composite and separation in the cold rolling process is established through the secondary development of MARC software. Based on this model, the important role of interfacial shear stress in the cold rolling composite process was revealed, and the composite mechanism was improved, through this mechanism, the reasons for the influence of material properties and reduction rate on the composite process were explained.
