多材料产品的特点是通过结合至少两种不同材料的特定优点来实现复杂的性能概况。双金属铸造是一种能源和材料效率高的技术，用于生产多金属物体。本文介绍了在铜锡合金（CuSn6）和纯铜（Cu99.5）界面上形成具有内聚结合特性的旋转对称双金属的半连续铸造工艺的发展。通过静态铸造进行了初步试验，以评估热过程窗口。在初步试验结果的基础上，开发了一种垂直半连续复合铸造工艺。通过在界面处形成固溶体，在接合体之间形成稳定的内聚键。本文是《铜及其合金专题》的一部分。
Multiple-material products are characterised by a complex property profile which is achieved by combining the particular advantages of at least two different materials. Bimetal casting is an energy- and material-efficient technology for the production of multi-metallic objects. This paper describes the development of a semi-continuous casting process for the formation of a rotationally symmetric bimetal with a cohesive bonding character at the interface of a copper-tin alloy (CuSn6) and pure copper (Cu99.5). Initial experiments are conducted by static casting to evaluate the thermal process window. Based on the results of the initial experiments, a vertical semi-continuous compound casting process is developed. A stable cohesive bond between the joining partners is accomplished by forming a solid solution at the interface. This paper is part of a Thematic Issue on Copper and its Alloys.
