5 ESSENTIAL ELEMENTS FOR DIFFUSION BONDED CRYSTAL

The fracture actions and fracture mode on the diffusion-bonded joints had been elucidated by macro fracture and magnified area morphologies. The macro fracture morphologies (flat fracture) show the propagation of crack happened alongside the MEA/DD5 interface in tensile checks from the joints realized at 1020, 1050, and 1080 °C (Determine 8a–c).
