项目摘要
Metallic composite materials are of great technical importance. They allow to combine specific positive properties of different materials into one component. In recent years research on the production of copper-aluminum-composites via composite casting has been done with the purpose of combining the excellent electrical and thermal properties of copper with the low density, price and the also good electrical properties of aluminum.Up to now the basic correlations between processing conditions, metallurgic processes and resultant properties of the composites have not been investigated sufficiently. Therefore it is difficult to evaluate or predict the suitability of cast Cu-Al-composites for further metal forming processing. Of particular interest are the effects of the thermic conditions inside the composite zone on the formation of the boundary layer and the technological properties. Furthermore no numerical models exist to simulate the resulting microstructure in the composite zone.Therefore basic knowledge and comprehension of the physical mechanisms of the formation of the boundary layer in dependence on the casting conditions are necessary. For this purpose basic bilayer-composite-casting experiments will be applied to ensure a repeatable production of Cu-Al-composites under varying casting conditions. In addition a simulation model to predict the resulting microstructure in dependence on the casting conditions will be developed and validated. All in one the comprehension of the correlations between the microstructure, the physical and technological properties and the suitability for further metal forming processing of cast Cu-Al-composites has to be enhanced.
金属复合材料具有重要的技术意义。它们允许将不同材料的特定正性能组合成一个组件。为了将铜优异的电学和热学性能与铝的低密度、低价格和良好的电学性能相结合,近年来进行了复合铸造生产铜铝复合材料的研究。到目前为止,对复合材料的加工条件、冶金工艺和合成性能之间的基本关系还没有进行充分的研究。因此,很难评价或预测铸态cu - al复合材料对进一步金属成形加工的适用性。特别令人感兴趣的是复合区内的热条件对边界层形成和工艺性能的影响。此外,没有数值模型来模拟复合区的微观结构。因此,有必要了解和理解边界层形成的物理机制与铸造条件的关系。为此目的,将应用基本的双层复合铸造实验,以确保在不同铸造条件下可重复生产cu - al复合材料。此外,还将开发和验证一个模拟模型,以预测依赖于铸造条件的最终组织。总之,对铸态cu - al复合材料的微观组织、物理性能和工艺性能与进一步金属成形加工的适用性之间的关系的理解必须得到加强。
