FASCINATION ABOUT DIFFUSION BONDED CRYSTAL

The fracture behavior and fracture method on the diffusion-bonded joints have been elucidated by macro fracture and magnified floor morphologies. The macro fracture morphologies (flat fracture) reveal the propagation of crack happened along the MEA/DD5 interface in tensile assessments from the joints realized at 1020, 1050, and 1080 °C (Figure 8a�
