Creep resistant pressure cast zinc alloys

与铁、铝或镁基材料相比，迄今为止，锌合金仅被少量研究，因此，尚未对其作为结构材料的潜力进行充分评估。由于锌的熔化温度低至420°C，室温已经是高的同系温度;因此热激活过程可以在环境温度下容易地进行，并且通常会导致使用中的铸件软化。该项目的目标是开发一种计算机引导的合金和工艺策略，用于选择和优化锌合金的机械性能，特别是改善耐老化和抗蠕变性。在热力学和动力学计算预测的基础上，将通过压力铸造生产合金，研究其机械性能并迭代优化。

In contrast to iron, aluminum or magnesium base materials, zinc alloys have been investigated only marginally so far and therefore, have not been fully evaluated with respect to their potential as structural materials. Because of the low melting temperature of zinc of 420°C, room temperature is already a high homologous temperature; hence thermally activated processes can easily proceed already at ambient temperature and generally cause a softening of a cast part in service. It is the objective of this project to develop a computer guided alloy and process strategy for the selection and optimization of the mechanical properties of zinc alloys, in particular an improvement of the aging and creep resistance. On the basis of predictions of thermodynamic and kinetic computations, alloys will be produced by pressure casting, investigated with respect to their mechanical properties and iteratively optimized.
