DIFFUSION BONDED CRYSTAL NO FURTHER A MYSTERY

The fracture conduct and fracture method of the diffusion-bonded joints have been elucidated by macro fracture and magnified surface morphologies. The macro fracture morphologies (flat fracture) exhibit the propagation of crack happened along the MEA/DD5 interface in tensile exams with the joints achieved at 1020, 1050, and 1080 °C (Figure 8a–c)
