THE BEST SIDE OF DIFFUSION BONDED CRYSTAL

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