| Abstract Scope |
Composition gradient in complex materials system is critical to reach desired functions while mitigating failures due to property mismatch. Gradual chemical composition change from electrode to electrolyte in fuel cell applications has been reached by a customized direct energy deposition, adjusting the mixture ratio of powders in real time. Complex microstructure requires a new visualization tool to represent the heterogeneous microstructure. A new visualization tool was invented to capture the microstructure feature variation in the complex heterogeneous materials, such as composition gradient material system. This is also applied to represent texture (crystal orientation distribution) gradient materials, which is common in most formed or fabricated materials, even after post treatment. Macrotexture map was invented to represent the texture heterogeneity in polycrystalline material using weights of texture descriptors as color code picker. This tool will find application in microstructure representation, property simulation, and materials design. |
