ABS>The mechanical properties (stress values for various types of strain, ductility, and hardness) for welds in Nibase alloys were investigated over a broad range of temperatures, -320 to +2200 deg F. The type of weld was either argon shielded or covered-electrode shielded, and the alloys studied were of the Ni-Ti, Ni-Cr-Fe-Nb, Ni-CrFe-Ti, and Ni-Cu types. Graphs of all the data are given together with numerous microphotographs of the alloy structures. The results found were: Ni-Ti welds have a low-ductility dip centered at 1800'F; Ni- Cr-Fe-Nb welds have maximum hot ductility of the welds studied as well as excellent ductility and strength at low temperatures (which Ni-Ti and Ni-Cu also possess); Ni-Cr-Fe-Ti welds are hot brittle and crack sensitive; and Ni-Cu welds have low ductility above 1200 deg F, but high ductility below 800 deg F.
