DIFFUSION BONDED CRYSTAL NO FURTHER A MYSTERY

The fracture conduct and fracture mode from the diffusion-bonded joints ended up elucidated by macro fracture and magnified surface morphologies. The macro fracture morphologies (flat fracture) exhibit which the propagation of crack transpired together the MEA/DD5 interface in tensile assessments from the joints realized at 1020, 1050, and 1080 °C
