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

Abstract

The local effects of stress from a mechanical indentation have been studied on a Ni3 Al single crystal containing submicron inclusions of molybdenum fibers. Polychromatic X ray Microscopy (PXM) was used to measure elastic and plastic deformations near the indents. Analysis of freshly acquired massive sets of PXM data has been carried out over the Science Studio network using parallel processing software 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 Ni3 Al and the Mo phases, particularly around 8 indents patterned at the longitudinal section of the alloy.
