sdss_austenite#

orix.data.sdss_austenite(allow_download: bool = False, **kwargs) → CrystalMap[source]#

Return a single phase Austenite crystallographic map produced with dictionary indexing of electron backscatter diffraction patterns of a super duplex stainless steel (SDSS) sample containing both Austenite and Ferrite grains.

Parameters:

allow_download: Whether to allow downloading the dataset from the internet to the local cache with the pooch Python package. Default is False.
**kwargs: Keyword arguments passed to file_reader().

Returns:

xmap: Crystal map of shape (100, 117).

Examples

Read only refined orientations from the EMsoft HDF5 file by passing keyword arguments on to the reader and plot the dot product map
