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 area morphologies. The macro fracture morphologies (flat fracture) exhibit that the propagation of crack transpired along the MEA/DD5 interface in tensile exams with the joints attained at 1020, 1050, and 1080 °C (Figure 8a–c).
