| Abstract: | The processing of superplastic forming (SPF) and diffusion bonding (DB) of Inconel 718 alloy for fabricating rocket engine parts is presented in this paper. Testing results indicate that specially proceeded, fine grained Inconel alloy shows sufficient superplasticity for SPF of considerably complex parts. It has shown that the inconel 718 alloy can be diffusion bonded by using a nickel interface layer to form high shear strength bonds. |
