NOT KNOWN DETAILS ABOUT DIFFUSION BONDED CRYSTAL

The fracture actions and fracture mode with the diffusion-bonded joints were elucidated by macro fracture and magnified floor morphologies. The macro fracture morphologies (flat fracture) show which the propagation of crack occurred along the MEA/DD5 interface in tensile assessments of the joints obtained at 1020, 1050, and 1080 °C (Figure 8a–c)
