Based on the results of the research of local orientations measured by EBSD/SEM for AA1050 and AA3004 aluminum alloys (made in the system y-x: for cross-section ND-TD or TD-ND) I made studies of transformation of these data into rolling system TD-RD and I created a tool to verify correctness of these transformations. Based on the analysis of texture data for the calculated percentage shares texture components defined as: 'Copper','S', 'Goss','Brass',I could draw the following conclusions:
- You can get data on percentage shares of individual texture components in the rolling system (for plane TD-RD) by performing measurements of local orientation (EBSD maps) in a plane perpendicular to the RD direction (RD is parallel to ED in ECAP die) and transforming it accordingly;
- The analysis of change of texture components in function of 1-hour annealing temperature (from 100°C to 400°C) for AA1050 and AA3004 aluminium alloys showed no correlation (too small region taken to the measurement);
- To obtain reliable data, the measurement should be made over a larger area - should cover a wider range of microstructure (our area was 10x10µm2);
- Verification of the results should always be made based on a different method of measurement, in our case, we will survey the entire surface of the sample using X-ray diffractometer.
