Spatially Mapping the Properties of Heterogeneous Materials States for Advanced Materials and Manufacturing
Abstract
Funds are provided to purchase, install, and integrate an automated micro hardness indenter system. This project addresses directly the objectives to enable universities to purchase relatively high-cost research instrumentation that is normally not included in si ngle-investigator research grants.The response of materials to stimuli (e.g., mechanical properties) is inherently inhomogeneous a t a length scale commensurate with the materials microstructure. The inhomogeneity can be either desirable or undesirable. For examp le, in structures where the surface properties have been enhanced through engineered chemical or physical modification, the variatio ns are desirable. However, where variations occur due to subtle differences in microstructural evolution during materials processing , the variations are ignored (at best) or act as a potential weak link and place for subsequent failure (at worst).
