| Abstract: | In this study, the in-situ synthesis of intermetallic compound NiAl was studied. The pressed blanks of blended Ni-Al elemental powders were synthesized by pressurized combustion synthesis technique. The superalloys based on nickel had successfully bonded on the Gleeble-1500 thermal-mechanical simulation tester. The tensile test of the joint was done. The microstructure of the joint interface was investigated. The fracture of the joint was also analyzed. |
