FASCINATION ABOUT DIFFUSION BONDED CRYSTAL

The fracture habits and fracture mode in the diffusion-bonded joints ended up elucidated by macro fracture and magnified area morphologies. The macro fracture morphologies (flat fracture) exhibit which the propagation of crack happened along the MEA/DD5 interface in tensile checks in the joints obtained at 1020, 1050, and 1080 °C (Figure 8a–c).
