| Abstract Scope |
Sheet lamination additive manufacturing is a novel process, pioneered in the 1990’s, that leverages Fick’s laws of diffusion to join intricately cut sheet components to form a three-dimensional structure that cannot be produced with traditional manufacturing techniques. This method has been used by the aerospace, automotive and nuclear industry to manufacture complex heat exchanges, fluidic valves, and specialized components that cannot be manufactured using traditional techniques.
This study simulates the joining of Inconel alloy 718 laminates with the solid state and transient liquid phase diffusion welding process with and without the aid of an interlayer materials. Interlayer materials aid bonding by introducing a strong concentration gradient however they locally introduce new elements into the material which can effect mechanical properties. This study attempts to bond alloy 718 without drastically changing the composition and mechanical properties of the material by using thermodynamic modeling, and experimental testing to validate the models developed. |
