摘要(Abstract)：

采用真空热压设备制备了铜-碳钢层状复合材料，分析了扩散温度与保温时间对其界面扩散行为的影响，并建立扩散模型，计算了不同扩散温度和时间下Cu向Fe中的扩散距离。结果表明，铜-碳钢结合紧密，形成了明显的扩散层；随着扩散温度由730℃升高到810、856和912℃,Cu/Fe-C(1.2 mass%)界面的Cu、Fe元素的互扩散距离呈先减小后增加的趋势；当扩散温度为856℃时，延长保温时间Cu/Fe-C(0.2 mass%)界面扩散层厚度均在1μm左右；理论计算结果与实验数据的对比发现，实际扩散距离小于理论计算值，这是由于Cu/Fe-C(0.2 mass%)界面的扩散行为受到制备工艺、钢材含碳量等多种因素影响。
