Deformation and fracture behaviour, and thermal stability of ODS-Cu/ODS-Cu and SUS/ODS-Cu joints fabricated by advanced brazing technique

•To understand the excellent joint mechanism of the GlidCop®/GlidCop® and SUS/GlidCop® joints through the AMSB fabrication technique, deformation and fracture behaviour of the GlidCop®/GlidCop® and SUS/GlidCop® joints were investigated.•In the case of the GlidCop®/GlidCop®, deformation occurred predominantly in the diffusion layer with lower hardness, and the fracture proceeded almost at the center of the layer.•In the case of the SUS/GlidCop®, deformation occurred widely in both bulks near the bonding layer. The fracture proceeded mainly along the interface between the GlidCop® bulk and the bonding layer.•The diffusion layer and bonding layer showed an excellent thermal stability against a repetitive heat treatment.
