Acquisition, Sharing, and Processing of Large Data Sets for Strain Imaging: An Example of an Indented Ni3Al/Mo Composite

The local effects of stress from a mechanical indentation have been studied on a Ni3Al single crystal containing submicron inclusions of molybdenum fibers. X-ray microdiffraction (PXM) was used to measure elastic and plastic deformations near the indents. An analysis of freshly acquired massive sets of PXM data has been carried out over the Science Studio network using parallel processing software called FOXMAS. This network and the FOXMAS software have greatly improved the efficiency of the data processing task. The analysis was successfully applied to study lattice orientation distribution and strain tensor components for both the Ni3Al and the Mo phases, particularly around eight indents patterned at the longitudinal section of the alloy.
