Morphological Analysis and Its Applications in Materials Science and Engineering

Morphological analysis and synthesis operations were employed for understanding microstructure transformations and evolution for a number of materials science problems:

     1. the application of charge/discharge cycles to electrochemical storage systems (batteries);
     2. Morphology based metallic surface characterization (metrology);
     3. Fracture surface analyses and decomposition into brittle and ductile failure;
     4. Defect identification for material components,
and many others.

     Using the patented state-of-the-art morphological algorithms and platform, the MorphoHawk (TM) , it becomes possible to predict and analyze microstructure evolution and transformations using this original mathematical approach. The developed techniques could be considered supplementary to a phase-field mesoscopic approach to microstructure evolution that is based upon clear and definitive changes in the appearance of microstructure. However, unlike in phase-field, the governing equations for the morphological approach are geometry-, not physics-based. A similar non-physics based approach to understanding different phenomena was attempted with the introduction of cellular automata. It is anticipated that morphological synthesis will represent a useful supplementary tool to phase-field and will render assistance to unraveling the underlying microstructure-property relationships.
