Hi Saeed, analysis of suface step formation can work!? But for ths alloy no paper is findable. :-(

Saeed, I think you should look at the papers by the group of Prof. Sehitoglu. My former PhD student L. Patriarca is working on this topic: they apply DIC.

Thank you Dear Dr. Klemm and Dr. Beretta.

I followed your suggestions but I could not find the answer of my question. As I checked, the works of Prof. Sehitoglu are about modeling of deformation modes with an emphasis on shape memory alloys. In addition, their validating experiments are microscopy methods.

Since that in beta titanium alloys, mentioned deformation products have a similar appearance, I'm looking for experimental methods which can discriminate between them.

You're right, but to work this problem without electron microscopy is not such good idea and no simple task. XRD would also work. There are two interesting new paper on which I have unfortunately no access:

You can try in situ testing in an SEM coupled with EBSD studies

Dear Dr. Klemm,

Many thanks for your interest and useful comments. I know that the microscopy especially EBSD is the best approach, but unfortunately I have no access to EBSD or TEM.

Hi Saeed Sadeghpour, for the analysis of these microstructural characteristics you will need to use EBSD, TEM, or DIC is a good technique.. I´m sure a collaboration with other research group or institution could solve your issue.

Regards,    

Hi Dr. Garcia-Sanchez, many thanks for your comment. I am looking for an active group in this field to collaborate with but I haven't been successful yet.
