摘要
对Al-4.45Cu-1.50Mg合金进行室温条件下冷轧和随后180℃时效加工,利用拉伸试验机、透射电子显微镜(TEM)等研究冷轧态Al-Cu-Mg合金的显微硬度变化、力学性能和原子尺度的合金内部微观结构。结果发现,室温冷轧后时效态Al-Cu-Mg合金出现双峰强化现象,并阐明双峰强化机制。
A1-4.45Cu-1.50Mg alloy was subjected to cold rolling at room temperature and then aged at 180 ℃ for different time. Tensile test machine, optical microscope （OM） and transmission electron microscopy （TEM） were used to study the properties and microstructure of the A1-Cu-Mg alloy. Strengthening phenomenon of double peaks aging was found in the cold rolled and aged aluminum alloy, and the mechanism of strengthening was illustrated.
