DIFFUSION BONDED CRYSTAL SECRETS

The fracture habits and fracture mode on the diffusion-bonded joints were elucidated by macro fracture and magnified area morphologies. The macro fracture morphologies (flat fracture) demonstrate that the propagation of crack happened along the MEA/DD5 interface in tensile assessments with the joints obtained at 1020, 1050, and 1080 °C (Figure 8aâ
