These data were collected by Ying Pang as part of her doctoral dissertation (2005) at Carnegie Mellon University. Two samples are compared: 99.99 % rutile and 2 m/o Nb-doped rutile. Orientation maps were collected by EBSD. Details of the sample preparation and analysis can be found in the two papers cited below.
