腐蚀和疲劳的叠加作用将减小铝合金使用寿命。为了定量描述腐蚀对7075-T6铝合金的强度和疲劳寿命的影响。实验用1.6mm厚的7075-T6板(与飞机机体使用板厚度相同)加工成304.8mm×76.2mm的样品,中心测量段尺寸63.5mm×50.8mm。样品长度方向平行于板择优取向。用耐蚀苯贴于样品表
The combination of corrosion and fatigue will reduce the life of aluminum alloy. In order to quantitatively describe the effect of corrosion on the strength and fatigue life of 7075-T6 aluminum alloy. The experiment used a 1.6mm thick 7075-T6 plate (the same plate thickness as the aircraft body) machined into a 304.8 mm x 76.2 mm sample with a central measurement segment size of 63.5 mm x 50.8 mm. The length of the sample is parallel to the preferred orientation of the plate. With corrosion-resistant benzene affixed to the sample table
