Abstract: The micro-morphology of the elastic sling sample of copper-magnesium alloy broken during operation was observed by scanning electron microscope and metallographic microscope, the corrosion products on the surface of the sample were analyzed by energy dispersive spectrometer, and the simulation test of cold pressing welding of copper-magnesium alloy was carried out.Determine the abnormal structure at the fracture of the material. The results show that the failure mode of the sample is corrosion f... More
