文摘

The 50Mo-50Re alloy thin sheet was brazed successfully by vacuum brazing method. δ-Ni(Mo, Re) and Г1-Ni(Mo, Si) were the main formed phases existed in brazing seam of the joint of 50Mo-50Re/Ni-Cr-Si-B. Fracture characteristic in the interface was a mixed intergranular and transgranular fracture.
