Hi everyone,
I needed to perform a microstructure study of a Ti6Al4V sample. After polishing with SiC sheets, diamond paste and finally with colloidal silica I etched the sample surface with Kroll's reagent. The microstructure I obtained is provided below.
From the time I have observed I am puzzled as to see a strip of elongated grains, longer and smaller than the surrounding regions with more of a vertical alignment. From literature I see that there are some explanations as to the formation of grains of specific shapes based on heating and cooling and deformation cycles but I expect it to occur uniformly in entire regions not in strips.
Can you guys provide your thoughts on their occurrence?
