Figure 12
Electron microscopy images showing the compressed section and copper tube after continuous immersion for 168 hours. The left column displays the pressure-bearing section with three labeled images numbered 1, 6, and 5. The right column displays the copper tube with corresponding images. Each image shows detailed textures and structures at different magnifications, with scale bars indicating 10 micrometers for the top row and 20 micrometers for the bottom rows.Electron microscopy images of the compressed section and copper tube after continuous immersion for 168 hours.
