| Abstract Scope |
While it has long been possible to make gradient materials, there are challenges associated with the design and assurance that the designed material has been placed in the spatial coordinates desired. This talk will present an overview of the challenges and opportunities associated with gradient materials. With respect to manufacturing, this talk will describe the challenges and opportunities associated with spatially controlling composition, adapting process parameters for the local material composition, and adapting measurement techniques accordingly. With respect to measuring, we will address the challenges and opportunities of both in-situ and ex-situ measurements, ranging from mechanical testing to NDE techniques. With respect to modeling, we will address modeling approaches that range from thermodynamic strategies to design gradients to avoid deleterious phases to modeling of elastic and plastic deformation in gradient materials. |
