Ametek Edax OIM Matrix Software Enables Electron Backscatter Diffraction Simulations and Dictionary Indexing

Ametek Edax has introduced the OIM Matrix software package, which brings dynamic diffraction-based electron backscatter diffraction (EBSD) pattern simulations and dictionary indexing capabilities to the EBSD market. The OIM Matrix package allows users to simulate EBSD patterns based on the physics of dynamical diffraction of electrons. This approach more accurately describes the behavior of the electron interactions within a sample and produces more realistic pattern simulations compared with traditional kinematic-diffraction-based approaches. These simulated patterns can then be more easily and accurately compared with experimentally collected EBSD patterns.

OIM Matrix can be used to create a library of EBSD patterns for all crystallographic orientations for a given material. Experimental patterns can then be compared and matched with the best-fitting pattern in the library, in...
