WHAT DOES DIFFUSION BONDED CRYSTAL MEAN?

The fracture actions and fracture mode of your diffusion-bonded joints have been elucidated by macro fracture and magnified area morphologies. The macro fracture morphologies (flat fracture) show the propagation of crack happened together the MEA/DD5 interface in tensile tests with the joints accomplished at 1020, 1050, and 1080 °C (Figure 8a–c)
