LITTLE KNOWN FACTS ABOUT DIFFUSION BONDED CRYSTAL.

The fracture conduct and fracture manner of the diffusion-bonded joints had been elucidated by macro fracture and magnified surface morphologies. The macro fracture morphologies (flat fracture) show that the propagation of crack happened together the MEA/DD5 interface in tensile assessments on the joints reached at 1020, 1050, and 1080 °C (Figure
