Phase discrimination by pattern brightness in EBSD mappings

A new method that allows identifying different phases with a similar crystal structure without using information from the EDS detector was developed. The method is based on the thermal diffuse scattering (TDS). Experimental tests were conducted on Mg-2Y-Zn and AA3105 alloys to validate its applicability to discriminate different phases in different alloys. The results showed clearly that the new method is more accurate and faster than other conventional methods.
