an issue about beta phase reconstruction

[2mapril]

Hi,
I'm working on the beta phase reconstruction in titanium, the material I have been studying is a near-alpha titanium, which is constituted of primary alpha and secondary alpha, so I screened out primary alpha in Aztec and saved those secondary alpha as a new project (format: .cpr)，but when I use the code in Parent Beta Phase Reconstruction in Titanium Alloys, reconstructed beta phase seems to appear at where primary alpha exsists, as shown in Fig.1. But the new project saved in Aztec shows almost 50% not-indexed solution, which means no primary alpha.
What's even more puzzling is that after running nearly whole code, there are 40%~50% alpha phase remained, as shown in Fig.2. But using Parent grain analysis in Aztec, the remained alpha phase reconstructed from the Project only contained secondary alpha phase only has 2%.
Has anybody encountered kind of problem？Are there any parameters that I should adjust for better reconstruction?
I will much appreciate you for your generous help!!

I cannot download the word file, but generally I would advise not to remove 1 phase before importing into mtex. I would import the data into mtex and then split the data into two separate phases, and then perform the reconstruction in the way you want to. Mtex can then ignore the primary alpha and there should not be issues of beta appearing in weird places.

Thank you very much for your reply,Tijmenvermeij!!!And I tried what you advised, but the volume fraction of my titanium only 0.3%, which means beta phase can not influence very much the constrcution process. I think I should try it in Aztec Crystal,but I'm quite confusing about the underlying princle for buttons in the app.

I'm not sure I completely understand what you are doing, but did you say that you export a map with only secondary alpha and then use that in mtex? If so, depending on your settings, parent grain reconstruction in Mtex probably fills up your empty space. It would be better to have also the primary alpha in MTex, as a different phase perhaps, so it is ignored in the reconstruction.
I would try to separate primary and secondary alpha within mtex, and then store it in 2 phases, and then do the reconstruction

Thank you very much for your advise, SUCH NICE OF YOU!!! it has been a long long time for reading my email since the last time! i found the reconstruction work going not very well(either in Aztec or in mtex), maybe it's because its a deformed material.   1022107270好 ***@***.***
