由于具有巨大的资源节约潜力，热挤压直接回收铝片是一种很有前途的替代高耗能重熔工艺的方法。通过力学准静态和循环试验，对AW6060铝合金铸基和切屑基试样的力学性能进行了表征。通过滞后、温度和电阻测量来跟踪材料的响应，从而可以通过交流电势降技术来估计疲劳强度。在光学和扫描电子显微镜下，显微组织中的缺陷以空洞和切屑之间的缝焊的形式产生的影响可以与疲劳性能相关联。
Due to a great potential for conserving resources, the direct recycling of aluminum chips by hot extrusion is a promising alternative to energy-intensive remelting process. The mechanical properties of cast-based and chip-based specimens of AW6060 aluminum alloy were characterized by means of mechanical quasi-static and cyclic experiments. The response of the material was followed by means of hysteresis, thermometric and resistometric measurements, whereby the fatigue strength could be estimated by alternating current potential drop-technique. The effects deriving from defects in the microstructure, in the form of cavities and seam welds between the chips, could be correlated with the fatigue properties by means of optical and scanning electron micrographs.
