| Fraction recrystallized vs. time and the corresponding EBSD maps for 5, 10, 20, and 30 minutes |
- Does Sigma 3 content actually increase based on fractions or just propagate/elongate with grain growth based on the length/number ratio?
- To better answer this, we should group the clusters of Sigma3 boundaries: This is achieved by taking the Sigma3 out list text file, and starting with the first line, find what endpoints it connects to (at most two more). But more importantly is to see how many more connections are formed since then. These connections should be stored as to eliminate any redundant "chains"
- Obtained CSL_filter programs to test for the behavior of Sigma 9 and Sigma 27 in more detail. Future proposed work (based on above) should be incorporate the "chain" behavior
- Other idea will be determine how this relates to the percolation theory, and secondly, how well this measurement of connectivity corresponds to Betti number / CHomP analysis
- Triple junction analysis data should be grouped into more general categories, but promising sign that the 3,3,9 fractions are increasing, and especially the coh3,incoh3,9 combination the most
- Take 10 coh3,coh3,9 boundaries, and zoom to a higher resolution and confirm that there is no such "bending" at the triple junction. Basically it is very unlikely for two fully coherent Sigma 3s to come together (but not impossible) to form the last Sigma 9 junction.
Things that were discussed with Professor Rollett:
- Re-plot graphs based on fraction recrystallized from the Hardness test measurements and not the grain orientation spread measurements
- Also plot the existing graph against fraction recrystallized rather than time to determine whether new boundaries are arising in the recrystallized areas or not
- Calculate the stored energy in the microstructure based on the GOS data and how that corresponds to grain boundary migration velocity
- Use the Avrami equation to determine both the number of recrystallizing nuclei (I) and also the rate of growth (G). How do these values compare to that which Yuan has produced?
- Is the fraction of Sigma 3 boundaries static in the deformed microstructure as expected? Also analyze how triple junction character changes in deformed area
