| 中文摘要: |
| 目的 研究在不同温度条件下Cu(商业纯铜)/Al(AA1060)/Cu复合板材累积叠轧过程中界面金属间化合物层对材料性能的强化规律。方法 在不同温度条件下(350~500 ℃)累积叠轧制备Cu/Al/Cu层状复合板材，深入分析其界面金属间化合物层形状、元素分布及其对力学性能的影响规律。结果 金属化合物层的厚度随着轧制温度的升高逐渐增加，且随着轧制温度的不同，形貌呈现很大的差异。当轧制温度为350 ℃和400 ℃时，金属间化合物相对平整。轧制温度升高到450 ℃时，金属间化合物层呈现锯齿形，使该工艺条件下加工的材料同时具有较好的强度(273 MPa)和塑性(4.06%)。结论 制备Cu/Al/Cu层状复合材料过程中，通过优化轧制温度这一重要轧制参数，能实现强度和塑性的综合提高。 |

| The work aims to study the strengthening effect of interfacial intermetallic compound layer on material properties during lamination of Cu (commercial pure copper)/Al (AA1060)/Cu composites at different temperature. Cu/Al/Cu laminated composites were processed by ARB (accumulative roll-bonding) at different temperature (350-500 ℃) and the shape and element distribution of intermetallic compound layer at interface and its influence on mechanical properties were analyzed. The thickness of intermetallic layer sharply increased with the increase of rolling temperature, and the morphology showed great difference with the different rolling temperature. When the rolling temperature was 350 ℃ and 400 ℃, the intermetallic layer was relatively flat. However, when the rolling temperature increased to 450 ℃, a serrated shape occurred, which led to the good strength (273 MPa) and the excellent elongation (4.06%) simultaneously. In the process of preparing Cu/Al/Cu laminated composites, optimizing the rolling temperature as an important rolling parameter can comprehensively improve the strength and plasticity. |
