ABOUT DIFFUSION BONDED CRYSTAL

The fracture habits and fracture manner in the diffusion-bonded joints had been elucidated by macro fracture and magnified surface morphologies. The macro fracture morphologies (flat fracture) reveal that the propagation of crack occurred alongside the MEA/DD5 interface in tensile assessments on the joints obtained at 1020, 1050, and 1080 °C (Dete
