Abstract Scope |
Far-Field High Energy Diffraction Microscopy (ff-HEDM) is often used to investigate the orientation and average strain of individual grains within a polycrystalline material. Additionally though, analysis of per-grain data can provide valuable insight into the intragranular heterogeneity, notably the per-grain Orientation Distribution function (ODF) and stress/strain orientation distribution function (SODF). However, extracting this information takes a significant amount of post processing and specialist knowledge and is not available to the typical HEDM user.
The purpose of this work is to significantly reduce the complexity of obtaining intragranular heterogeneity information by providing a high level generalized ODF and SODF solver for ff-HEDM data. This tool is written as an extension to HEXRD and is intended to help facilitate the rapid exploration by even casual users of distribution functions within single grains. Experimental demonstrations are provided to help highlight the questions that can be answered with this functionality. |
