Summary

Superplastic deformation has been employed to join nickel aluminide (Ni3Al) at temperatures of 1000–1200°C and strain rates ranging from 1 × 10−5/s to 5 × 10−3/s. Optimum joining was achieved at 1100°C for strain rates ranging from 1 × 10−4/s to 9 × 10−4/s. Corresponding flow stresses were 47–123 MPa with permanent strains ≈10%. the room-temperature stress-strain of the joined flexure bars made at 1100°C was similar to that of monolithic samples. the role of surface oxidation conducted at 1100–1200°C on the joint quality was also investigated.
